analyzing the operation and design of a jaw crusher using edem simulation software

analyzing the operation and design of a jaw crusher using edem simulation software

A jaw crusher is a device that reduces the size of various solid materials in many applications, including underground mining and mobile crushing applications mainly using the compressive force of the two jaws, one of which is stationary and the other is moving. The jaw crushers moving jaw undergoes two main types of motion, one resulting from the eccentric shaft movement, and the second from the toggle plate and the tension rod.

Using simulation and the Discrete Element Method (DEM) it is possible to model the complex crushing process in order to optimize the operation and design of the machine. In this post we look at a jaw crusher model that was set up in EDEM in order to show the type of analysis that can be performed with the software. The simulation focused on the options enabling a jaw crushers optimization using EDEMs Breakage Model (based on Tavares, UFRJ).

A continuous feed-rate was simulated in EDEM, which is crucial in analyzing the crushing of the ore, as the jaw crusher usually operates with uniform feeding and its crushing performance is dynamically affected by the fill level. [Video at the end of the post]

As you can see, EDEM provides different modelling options and flexibility for the simulation and performance analysis of jaw crushers and other crushing equipment, enabling design and process optimization and minimizing the need for physical prototyping.

Specifically, by using the resources and academic literature available for EDEMs Breakage Model (available to EDEM customers from the EDEM Forum) users can accurately simulate the crushing behavior of different materials such as iron ore, limestone and granulite of varying size according to their requirements.

EDEM provides the user with valuable information regarding the Diameter of the simulated crushed material at different locations inside the crusher during the simulation. A very useful feature of the EDEM Analyst is plotting the particle size data before and after crushing and obtaining the maximum particle size for each simulation, minimizing the need for sieve analysis.

The pressure and compressive forces experienced as well as the wear on the jaw crushers plates can also be obtained using EDEM. This allows optimization for the pitmans design and crushing angle, and better prediction and planning for each crushers maintenance.

By using a sensor in the EDEM Analyst, the discharge flow rate from the orifice can be measured, for varying parameters such as material type and discharge orifice width, providing useful data for the jaw crushers designers and operators.

Giorgos Antoniou is a 4th Year Mechanical Engineering with Renewable Energy MEng student at the University of Edinburgh. He joined EDEM in January 2019 as an Engineering Intern for 7 months and has been focusing on exploring and developing application examples of EDEM in the process manufacturing, mining and heavy equipment industries.

mobile crushers

mobile crushers

It was a German limestone quarry that saw the Worlds first mobile crusher. The idea was born to take advantage of a continuous belt conveyor haulage and eliminate the costly road construction and up-keeps on wet ground. Since then, the mining industry, mostly quarries have seen 100s ofmobile crusher installation crop-up most (70%) of which are under 1000 TPH and feed directly atthe excavator face.

An in-pit and mobile crusher facilitates the transport of crusher material (ore, stone, rock) out of the mining area via also mobile or portable conveyors. The type of primary crushing is done using any of the several types of crushers available today capable of taking coarse/large rocks:

The wordMobile has been coined to indicate any type of Movable crusher. Most mobilesystems of crushing equipment may consist of any crusher on tracks, wheeled frame or skid allowed it to crawl or walk. This does not make the mobile crushing equipment portable, it just makes it mobile in reference to the ore supply source. If you combinea hopper, rock feeder and conveyor to those crushers, you have a fully equipped and functioning mobile crushing plant.

A movable crusher is positioned in the mines center at the same mining level as it working face. Such a crusher is mobilized every couple ofyears to keep it economically close to the core mining operation.Highland Valley Copper is a good example of largemovable crushers (2) and the effort it takes to move a crusher that surely not portable.

A portable crusher is not like a portable item as we are accustomed to. It means a crusher you can take apart or disassemble and transport on a road or highway if necessary. This ambiguity in terminology might cause a small prospectors and miners might search the internet for portable crushers but not find anything they hoped to fit in their pick-up truck or trailer & a large mining contractor to only find hobby size crushers.

The crushing station of the modular crushercan be dismounted into light weight modules and reassembled to the desired located generally in under 30 days. Since the resulting modules will still push over 60 tons plus measureover 40, and the moving of such crusher still takes a month, the frequency of relocation is around 3 to 5 years apart.

The concept of mobile crushers is not new. Since their introduction about twenty-five years ago, mobile crushers have continued to gain widespread attention. Mobile crushers reduce minerals in the open pit mine to sizes which can be transported by belt conveyors thereby reducing or eliminating the need for truck haulage. Truck haulage is costly, often representing as much as 50% of the total mining cost. More than 80% of the cost of truck haulage is for fuel and lubricants, tire replacements, and operators wages, and it can be anticipated that the cost of these items will continue to increase at a steady pace. Compared to truck haulage, transportation by belt conveyor is more energy-efficient, less labor-intensive, and less subject to inflation. Therefore, mobile crushers, used in conjunction with belt conveyor systems, offer one of the most effective available methods of reducing energy consumption and mining costs.

A mobile crusher is a completely self-contained unit mounted on a frame, which is moved, by means of a transport mechanism, along the wall of the mine pit as mining progresses. Excavated rock is fed, by means of a shovel or a front-end loader, into the mobile crusher, where it is crushed to sizes which a belt conveyor can handle. The crushed material is delivered to a shiftable belt conveyor system, which follows the movement of the crusher.

The mobile crusher unit is moved on crawlers, rubber tired wheels, or hydraulically operated walking pads. Figures 1, 2, and 3 show three operational mobile crusher units that are moved, respectively, by crawlers, rubber tired wheels, and walking pads.

The crawlers can move the mobile crusher unit 300-500m/h (1000-1500 ft/hr) and can negotiate slopes up to 10%. They exert a soil pressure of 10-20 N/cm (14-28 psi) and can travel on difficult terrain.

The rubber tired wheels, each with its own hydraulic motor, can move the mobile crusher unit 500-1000 m/h (1500-3000 ft/hr). Since the tired wheels exert a greater soil pressure, approx. 40-90 N/cm (55-125 psi), they are used only where soil conditions permit.

The hydraulically operated walking pads offer low deadweight, high safety in difficult terrain, and great mobility in all directions. They can move the mobile crusher unit 60 m/h (200 ft/ hr) and exert a soil pressure of 15-25 N/cm (20-35 psi). Since they are subject to less wear and tear than the other transport methods, they require less maintenance. The walking pads can be operated synchronously by control from a central console.

Most of the commercial mobile crushers in operation today are designed for crushing limestone and have a theoretical output of 300-1000 metric tons per hour. A few larger units now in operation, which were designed for particular applications, have outputs of 1000-1500 metric tons per hour. Mobile crushers of still greater capacity are being developed in Europe.

Fig. #4 shows a typical cross section of a mobile crusher. Most mobile crusher units use hammer mills, impact crushers, roll crushers, or jaw crushers, but recent developments have made it possible to use standard gyratory crushers also.

Mobile crushers are of two types: direct-feed and indirect-feed. Direct-feed mobile crushers receive the material from front-end loaders, without using a feeder. If the front-end loader can not reach the top of the receiving hopper, an access ramp is used. The ramp can be part of the crusher assembly, moving together with the unit, or it can be an independent structure, moved on skids or on crawlers.

Indirect-feed crushers receive the material via feeders, usually of the heavy-duty, apron type. In many cases, the receiving hoppers are located at a lower elevation than the crusher inlet, and the material is fed into the crusher via an inclined feeder.

Crushed material is collected under the crusher, on a short apron or belt conveyor, which usually discharges onto a cantilevered swiveling conveyor. The swiveling conveyor delivers the material to a self-propelled bridge conveyor, which forms a connecting link between the mobile crusher and a shiftable conveyor and provides flexibility in operation.

Mobile crusher units usually come complete with dust collection systems, power substations, control panels, access platforms, stairs, means for weather protection, and a hoist structure, all of which add substantially to the weight of the units.

The decision whether to use a mobile crusher unit at the open pit or a conventional fixed crusher installation located elsewhere at the mine site must be made during the planning phase of the mining project. The decision will depend on many factors, including the type of mineral to be mined, the size reduction required, the annual capacity, operating schedule, and life span of the mine, the distance from the mine pit to the delivery point, and the difference in elevation between these two locations.

To determine the most efficient crushing and transportation system for a mining project requires a detailed engineering study which investigates all of the pertinent factors. As part of a study, we compared mobile crusher systems with stationary crusher systems and investigated several alternative systems for crushing and transporting limestone from the face of the mine pit to a screening station. Our investigation included visits to several mobile crusher installations in Europe, where we observed mobile crushers in operation and talked with plant personnel who had operated both mobile and stationary crushing systems.

We present below some of the conclusions of our engineering study and we also discuss the effects which the subsequent inflation and higher energy costs have had on the projections we made in the study.

In our mobile crusher system concept, the blasted limestone, 1500 x 0 mm (60 x 0), is charged by front-end loaders into the receiving hopper of the crusher and conveyed, via an apron feeder, to the impact crusher. The crushed limestone, minus 120 mm (-5), is collected on a discharge conveyor under the crusher and transferred to a slewing conveyor. The slewing conveyor discharges the material onto a 1050-mm (42-inch) bridge conveyor which moves on crawlers. The material continues to the screening station, via shiftable conveyors 1 and 2 and stationary conveyors 3 and 4.

In our stationary crusher system concept, the blasted limestone is loaded by 5.4 m (7-cubic yard)shovels into 36-T (40-ton) rear-dump trucks. The trucks carry the limestone to a stationary crusher located outside the pit. The crushed limestone is conveyed a short distance to the screening station by a 1050-mm (42-inch) conveyor.

When we made the study, we did not anticipate the rapid increases in the costs of energy and labor which we have experienced since. The revised escalation curves adjusted for these increased costs. It can readily be seen that the yearly cost increases projected for mobile crusher systems are lower than those projected for stationary crusher systems.

These constantly increasing costs make it more and more costly to operate stationary crusher-truck haulage installations. On the other hand, mobile crusher-belt conveyor system installations, being far less subject to these constantly increasing costs, are more economical to operate. Therefore, mobile crushers, used in conjunction with belt conveyor systems, should be seriously considered when planning new mining facilities. They should also be seriously considered when planning to increase efficiency in existing mining facilities.

The economies and flexibility of mobile crusher installations discussed above have raised the question of how these advantages can be introduced in mining operations where crusher capacities of 4000-6000 metric tons per hour are required and where only large gyratory crushers can be used.

The best way to utilize the economies and flexibility of mobile crushers in such operations is to use a semi-mobile gyratory crusher unit, located in the mine pit but at some distance from the blasting and digging area. This separation of the crusher unit from the digging area is dictated by the high crusher capacity required. If the crusher unit operated in the digging area, the shovel or front-end loaders would not have enough room to feed directly to the crusher the large tonnages required. Therefore, the semi-mobile gyratory crusher unit is located at a relatively short distance from the blasting and digging area and is fed by trucks.

The trucks are rear-dump trucks, which are loaded by shovels or by front-end loaders, as in conventional operations. The trucks carry the blasted material from the blasting area to the crusher. It is important that the mining operation be planned so that the trucks have to travel only relatively short distances and that they do not have to negotiate prolonged haulage uphill. The semi-mobile crusher units are designed in such a way that they can be fed by rear-dump trucks.

Every six months to two years, depending on the progress of the mining operation, the semi-mobile crusher unit is moved from one operating location to another, by means of an independent transport mechanism.

Several European manufacturers are actively engaged at present in the designing phase of larger high-capacity, semi-mobile crushers. To give an idea of the direction this planning is taking, we present below descriptions of three different approaches for using semi-mobile crushers in high-capacity mines.

Fig. 9 shows a semi-mobile crusher unit, with a gyratory, operating adjacent to a specially built embankment. The crusher is fed by rear-dump trucks, which drive on the embankment and can converge on the crusher from three directions. The crushed material is collected on an apron conveyor under the crusher and is transported to a location outside the pit.

As the mining operation progresses, the distance from the truck loading area to the crusher unit increases to the point where it becomes more economical to relocate the crusher in order to shorten the truck haulage distance. At that point, a new embankment is prepared, and the crusher is moved to the new location, by a hydraulically operated walking pad mechanism or by an independent heavy-duty crawler-transporter like the ones shown in Fig. 10. This type of transporter has been recently developed for transporting heavy equipment in the lignite fields of West Germany.

The transporter rides under the crusher supporting structure, lifts the entire assembly approximately 0.6 m (24 inches), and carries it to the new location. The carrying platform of the crawler-transporter rests on jack cylinders which absorb the vertical forces of the load, and is guided by a center pin which absorbs the loads horizontal forces. When loaded, the crawlers man transporter exerts a soil pressure of 20 N/cm (28 psi) and can travel about 12 m/min (40 feet/minute). Unloaded, it exerts a soil pressure of 5 N/cm (7.0 psi) and can travel about 25 m/min (80 feet/minute). It can move on difficult terrain and can negotiate slopes of up to 10%. A hydraulic system, driven by a diesel engine, provides the power for lifting and travel. In addition to moving semi-mobile crushers, the crawler-transporter can move other heavy equipment within the mine, such as transformers, drive and tail sections of shiftable belt conveyors, and miscellaneous equipment components.

The crawler-transporter is the largest commercial unit now available and can carry loads of up to 1000 metric tons. To move semi-mobile crushers heavier than 1000 metric tons, two or three crawler-transporters can be used. Crawler-transporters with capacities greater than 1000 metric tons are now being designed in Europe.

A second type of semi-mobile crusher unit consists of two sections: the feed section and the crusher section. The feed section consists of a feed hopper for receiving material from rear-dump trucks, an apron conveyor for elevating the material to the crusher, electrical gear, and a supporting structure. The crusher section consists of a gyratory crusher, loadout conveyor, spillage conveyor, dust collector, and supporting structure. While in operation, each section rests on pontoons, and the two sections are docked together to form one operating unit.

Fig. 11 shows the feed section of this type of semi-mobile crusher as it is being moved to its operating position on four wheel assemblies. Each assembly consists of a hydraulically propelled wheel, 2.8 m (9.2 feet) in diameter, and a hydraulic lift cylinder. During operation, the wheel assemblies are retracted or removed, and the feed-section rests on a supporting structure. The wheel assemblies are bolted to the feed section and can be detached and used to move the crusher section.

The two sections of semi-mobile crushers can also be moved by the fork-lift, piggy-back transporter shown. A hydraulic system, driven by a diesel engine, powers the lifting and steering cylinders and the hydraulic motors for propelling the wheels. The transporter is positioned under one of the sections of the crusher unit. It lifts the section approximately 0.6 m (24 inches) and carries it, piggy-back fashion, to the new location, where it lowers the section into operating position. The same procedure is followed for the second section of the crusher unit. When loaded, the transporter can travel about 360 m/h (1100 feet/hour) and can negotiate slopes of up to 10%. Today, fork-lift, piggyback transporters are available for service loads of up to 1000 metric tons.

The third type of semi-mobile crusher unit, also consists of a feeder section and a crusher section. The crusheris a coal breaker, but a gyratory crusher can also be used if the inclined feeder is made long enough to accommodate the greater height of the gyratory crusher.

As in the case of the two semi-mobile crusher units described immediately above, the material is transported from the mine face to this crusher unit by rear-dump trucks. The trucks dump the material into the hopper of the feeder section, which rests in a specially excavated trench and which has a capacity equal to the capacity of three trucks. The material is conveyed from the hopper to the crusher by a heavy-duty apron feeder. The crushed material is transported by belt conveyors to a point outside the mine pit. When it becomes necessary to move the crusher unit to a new location, the two sections are moved separately by crawler-transporters or by specially designed stradle carriers.

The Fujiwara quarry has two quarries, upper quarry (elevation of 780 m above sea level) and lower (500 m above sea level). The upper quarry was developed in 1977 for installation of MCP. Recently the production ratio between the upper and lower quarry is 97:3 ; the MCP crushes the majority.

Coarse rock is crushed to minus 250mm and then dropped into the shaft by a spreader. From the shaft, the crushed rock is extracted by a roll feeder, installed at the bottom of the shaft, and is fed onto a belt conveyor. Materials, conveyed by belt is fed to a secondary crusher and reduced to minus 110mm. Crusher discharge is again conveyed by belt conveyor to the intermediate stockpile (capacity; 120,000 t).

At the start, because of initial trouble, a large amount of trouble time occurred for one year. Some defects are vibration, graveles dropping from pan-conveyors chink, breaking of drive shaft of the apron conveyors reduction gear, and breakdown due to overheating in the bush of the apron conveyors intermediate shaft..

In this mining method, if the haulage distance to MCP is over 150 m, MCP is moved to the piled rock to shorten the haulage distance and a shiftable belt conveyor is installed between MCP and shaft. Operating period of one block is from one and a half to two years.

The Taliesin Mod.Fab was designed and built by graduate and undergraduate students at the Frank Lloyd Wright School of Architecture with faculty guidance and an emphasis on prefabricated construction by Jennifer Siegal. The structure can be visited on the student-led Taliesin West Desert Shelter Tour.

OMD Joshua Tree exhibits the ideas of prefabrication, flexibility,portability and compact spaciousness. Originally located at the heart of Venice Beachs trendy Abbot Kinney Boulevard, the building served as a prototypical model home and showroom to display OMDs new work. Relocated to the high desert of Joshua Tree - close the national park entrance - the Joshua Tree Prefab now nestles into 80 acres of arid off-the- grid wilderness.

More than just green and modern, the Joshua Tree Prefab demonstrates OMDs commitment to merging responsible design with new technologies and luxurious details. Its central kitchen/bath core divides and separates the sleeping space from the eating/living space in a compact assemblage of form and function. The steel frame structure, measuring 12 feet by 60 feet (720 sq ft) features a high sloping 12 foot 6 inch ceiling, and was trucked to its site and set on a temporary foundation.

The design utilizes green technologies such as tankless water heaters,radiant heat ceiling panels, and translucent polycarbonate sheets,balanced with high-end amenities like the iPort integrated sound system, Boffi kitchen, and Duravit bathroom fixtures.Whether briefly situated in an urban lot, momentarily located in the open landscape, or positioned for a more lengthy stay, the Joshua Tree Prefab accommodates a wide range of needs and functions.

This 3,600 sf two-story modular residence sits on a flat lot in an Lconfiguration. While the street-facing front facade is compositionally compatible with neighboring houses, the long elevation facing the backyard features four large sliding glass doors. The garage opens to the front and the back yards for indoor-outdoor entertainment and other alternate uses. The lower floor is clad in light grey smooth stucco and the upper floor has vertical metal panels. The standing seam butterfly metal roof slopes to spatially increase the upper floors interior volume.The house contains 4 bedrooms and 2.5 baths. The first floor is dominated by the 670 sf open living-dining- kitchen space, with a study/guest room and the garage. The kitchen is by Boffi. The first floor concrete floor acts as a thermal mass to retain heat collected during the day. Extensive glass windows and sliding doors, made possible by the long-span steel frame, open to backyard views. A white steel patio pavilion, with a fireplace and steel trellis roof, extends from the living room for outdoor use. The second floor contains three bedrooms plus an open family room, laundry, and two terraces.

This 16 foot wide, four-steel framed modular residence was carefully positioned onto its 25 x 100 narrow urban lot. The 2,330 sf two-story prefabricated house sits on a flat corner lot. Its southeast and southwest facades are prominently exposed to the immediate Santa Monica neighborhood in Ocean Park, while the other facades are enclosed and private. The lower floor is clad in light grey mooth trowel stucco and the upper floor has horizontal Hardiplank,a green fiber cement siding. The hovering butterfly metal roof and extended corner window break up the rectilinear mass. Exposed, painted, steel channels at the roof reveal the structural system within. The first floor contains an open living-dining- kitchen space facing a rear patio with large sliding glass doors. The garage provides tandem parking, because of the narrow site conditions. Bamboo floors are used throughout the house. The second floor contains two bedrooms, two bathrooms, an open office space (convertible to a third bedroom) and a terrace over the rear yard. The California native landscaping provides a visually stimulating compliment to the home and neighborhood.

More than just green and modern, the home demonstrates OMDs commitment to merging responsible design with new technologies and luxurious details.The home sits on a 10,000 sf ft site, with its courtyard design inspired by the LA climate.The 4 modular prefabricated steel frame structures, measuring 2400 sq ft feature high interior 10 foot 6 inch ceilings, and project a 4 foot deep exterior shade awning wrapping the internal West facing courtyard and street side. Two of the existing structures on the property were recycled and remodeled to become the master suite and bathroom, office, laundry and detached 820 sf ft garage. Bamboo floors, tankless water heaters, Duo-flush toilets and shade awnings are green features used all through the home. The master planning of the site includes OMDs landscape design employing native and drought tolerant plantings, creating a front yard of raised vegetable gardens and a center private courtyard for outdoor dining, fire place and splash pool.

This site-built house is a development of the original OMD Swellhouse.A modular grid of exposed steel columns and beams orchestrates the spatial and structural design of this open live-work project. A SIP (Structural Insulated Panel) system of prefabricated wall and roof panels provide further modular structural stability, as well as thermal and acoustic insulation. The prefabricated SIP panels were assembled in a remote factory, trucked to the site, and set in place manually.

This 3500 sf house has been separated into two buildings - the residence at Brooks Avenue and the garage with a recording studio above at the alley. The two structures frame a central courtyard. Two existing mature palm trees, and the 40 ft by 130 ft. lots setbacks determined the placement of the structures.

The steel frame allows for large expanses of glass at the first floor,where the plan is open for living, cooking and dining. The kitchen is by Linea. Each wall plane parallel to Brooks Ave. contains all glass with central sliding doors. The remainder of the first floor is clad with metal panels. The upper floors, containing bedrooms, bathrooms and the recording studio, are more enclosed for privacy and are clad in stucco.

Ceilings are high and the steel I beams are exposed on the interior. A radiant tube heat system warms the concrete floor at the first floor.The second floor contains Brazilian Cherry wood. The recording studio has been fitted out with specific acoustic treatments. Exterior balconies with Ipe wood decking face the courtyard in a mirror image. All mechanical, electrical, pool, and water filtration systems run along the east edge of the site.

The Big Sur PreFab perches at the top of 217 acres of California mountain wilderness. Designed to be independent, self-sufficient and closely connected to the landscape, this model prefab is a pioneer for green off-thegrid housing in the region. Venturing off from Highway 1, climbing past the Redwood forest and California native plantings,the site is revealed and the view back to the Pacific Ocean provides the setting for John Steinbecks ideal artist retreat.

The 2150 sq ft 2-story home is constructed with structural insulated panels (SIPs). The Big Sur PreFab introduces less material waste,faster construction time, a tighter building envelope, green finishes and higher insulating properties resulting in a lower total life-cycle cost of the home. The first floor open plan emphasizes the strong relationship between the indoor living/kitchen/dining/reading space with the outdoor patio and garden. West facing operable windows at the ground level and ceiling fans on the second level provide passive cooling year round while the house is heated with two Rais Malta wood burning stoves. Locally sourced Tan Oak flooring connects the two levels and combines the open tread stair with a built-in book wall.

The airy 12 ft high second floor includes two bedrooms connected by a master bathroom and studio/office facing North. An outdoor patio off of the studio and second bedroom establishes an area for private sunbathing and contemplation. Green finishes include LED lighting fixtures, penny cork flooring, reclaimed colored wood planking for the master beds headboard/closet wall, overstock hand crafted Heath Ceramic tile and a salvaged Clawfoot bathtub.

The folded standing seam metal roofline provides an armature to harness twenty solar PV panels and two solar thermal panels and creates passive shading from the southern sun angle. The board-formed concrete dog-leg- retaining walls contain the mechanical equipment, Phoenix solar water heater, batteries and inverters.

Additional green systems include on-demand Navien water heater, two operable skylights and a septic tank. Responding to the latest requirements from the California Department of Forestry and Fire Protection the exterior is clad with Hardie Panel Cemplank lap siding,offering an ignition resistant exterior skin. The irregular patterning and regional color hues are inspired by the surrounding climate where green, ochre, sand and brown meld with the blue mountain sky.

The Sanderling Waldorf Schools new campus is in Encinitas, CA. The campus sits on 5 acres with an adjacent wetland and will provide 24,000 sq ft of indoor space. The program includes 5 Nursery Classrooms; 8 Classrooms for Grades Kindergarten 8th; 3-4 additional Classrooms for Specialty Subjects (Eurythmy, Music, Handwork, Science, Woodwork); Administration Offices; Teacher and Parent Lounges; Full Kitchen; Library/Tutoring Room; and Restroom Facilities.

OMD believes that around every corner exists an opportunity for learning. Our prefab portables are tools for learning about sustainability, design, and the importance of our impact on the landscape. We feel that a beautiful and flexible campus encourages children to form a special relationship to and appreciation for their place of learning. We believe in an integral experience between the learning that happens inside the classroom and the one that happens outside. Our goal is for each individual child to feel a sense of importance and belonging on their new campus by providing wonderful outdoor spaces for socializing, gardening, playing, and discovering, as well as inspiring interior classroom environments.

Office of Mobile Design (OMD) has designed a new middle school campus to expand The Country Schools existing preschool and elementary school campus. Our concept for the project centers around educational, environmental and fiscal responsibility.OMD has put a fresh face on prefabricated classrooms by incorporating modern design sensibilities, making these buildings virtually indistinguishable from site-built structures. We employ sustainable systems such as abundant natural light, cross ventilation, eco-friendly materials, efficient lighting systems and integration with the surrounding landscape, making these buildings healthy environments from which to begin the learning process.

The three prefab buildings are composed of eleven steel-frame modules. Each contains metal siding and roofing, large operable windows and doors, Expanko (made from rubber and cork) and bamboo flooring, Biocomposite panel cabinetry (made from sunflower seed husks) and Homasote (made from recycled newspaper)wall cladding. High sloping 13 foot ceilings and pendant lighting enhances the spaciousness of the classrooms. The 960 sf central building houses the middle school offices and the library. The 2400 sf west building contains three classrooms, the language lab, lockers and toilet rooms. The science lab and art studio make up the 1930 sf east building. The art studio doubles as a multi-purpose community room at night.

Portions of the existing middle school have been renovated by OMD to provide offices, a faculty lounge, a new music room, and a faculty toilet room. The landscape was designed in collaboration with Mark Tessier Landscape Architecture and features outdoor classrooms and gathering space, an amphitheatre, raised vegetable garden beds, a butterfly garden a frog pond and a stream. The native plant families were selected to encourage learning through their seasonal changes.And, the introduction of an edible garden allows the children an opportunity to experience the agricultural life cycle.It was our sincere hope that each individual child would feel a sense of importance and belonging on their new campus by providing them with wonderful indoor and outdoor spaces for socializing, gardening, playing and discovering.

For its corporate headquarters, the extreme sports-oriented web site pie.com chose a bow truss loft space in Hollywood. The open plan of the 10,000 s.f.space houses the various functions of the business under one roof, and allows for a dynamic and free flow of [ideas, information, views, light,bodies] within that space. The program includes: reception lobby, conference room, work stations, executive offices, kitchen/dining, storage/copyroom,and brainstorming `base camp space.To distinguish work areas, a series of light, almost delicate structures appears throughout, curvaceous and translucent, snaking here and there to delineate places for meeting, sitting, eating, and working. Dotting this interior work-scape are clusters of bi-level, amoeba-like desks gathered in trios around slender electrical supply columns; the locations of these work stations are determined by the overhead cable suspension track that winds its way sinuously around the entire office. A large swirling drum of a conference room dominates the space, rising up to the sky like a wave in a great swell of vibrant blue and green. It is entered along the sweeping path of a grey-on- grey floor mural, by the LA pop artist Andre Miripolsky, that leads from the elevator doors, through the entry lobby, right into the eye of the drum.

Pie.com's business focuses on dynamic, competitive, and high-intensity extreme sports, such as snowbording, surfing, skateboarding, and BMX mountain biking. Though the design of pie.com's offices includes moving parts (rolling doors and wheeled desks), it avoids being a literal manifestation of such activities. Instead, the space achieves its sense of dynamism and action through a dramatic manipulation of architectural elements. As natural light pours in from large skylights and plentiful east-and west-facing windows, it skips across exposed beams and free-standing walls, backlights translucent partitions, silhouetttes the sometimes frenetic motions of workaday goings-on, and sets various areas aglow with the reflected colors of nearby walls. This complex interplay of materials, colors,forms, and light makes for an animated environment that fosters productivity, creativity, and fruitful collaboration.

This 6,720 sf development is located along Venice Boulevard in the City of Los Angeles. Designed for a creative book design and publishing company, the emphasis is on open floor plans and natural light. The 3-story building is designed using 9 cantilevered prefabricated steel frame modules ranging from 60-30 long. There are 2 internal stairways with roof access, 1 elevator and 12 car and 4 bicycle parking spaces.

The idea of building a house out of shipping containers is becoming familiar, though few designs manage it this elegantly and comfortably, especially for such an unexpected location. The residence is on a formally empty industrial lot in L.A.s Lincoln Heights neighborhood, on the edge of downtown and adjacent to the large arts cooperative called the Brewery. The construction team dug up existing concrete slabs and replaced them with a thick, wild combination of plants, which grow especially well since the site is on the original alluvial plain of the now asphalt-covered L.A. River. Siegal, a former Brewery resident, calls the site the enchanted garden for its dense plantings and seclusion from the street. The house is composed of four corrugated steel shipping containers, which had - like their uneven site, been sitting abandoned in the area. The containers sit on top of each other in twos, separated by a living space roofed with a steel surface that tilts with a change in grade between the houses two sides. They are fronted by a facade of thick glass sheets that are abutted to create the illusion of a continuous glass wall. This eclectic middle space is the heart of the project.The rooms floor alternates between concrete and dark cherry wood, and it is enlivened by a succession of changes in levels and an indoor koi pond fed by a waterfall made of stacked flagstone. Up-cycled from aluminum grain trailers, the sunken outdoor trailer becomes a lap pool. The four multipurpose containers hold equally adaptable bedroom/bathroom, entertainment room/library, dining room/study, and laundry/mechanical spaces.

The AERO-Mobile is a movable flexible exhibition and retail space made of recycled parts discarded by the aerospace industry. This impermanent architecture envisions buildings as a series of ULDs (Unit Load Device) up- cycled as exhibition space platforms, mounted on electric trucks, allowing for spontaneous pop-up experiences to be deployed throughout the city center and its surrounding suburban neighborhoods. Using social media and a new mobile App the AERO fleet is easily located or transformed as the functions for the artist, curator or merchant fluctuate. Visually engaging, the AERO-Mobile creates an individual or a communal outlet for instantaneous consumerism, complimenting and eflecting todays world where life is anything but static.

Truck-A- Tecture at KANEKO sets the stage for a debate on an unlikely pair of themes: prefabricated architectural solutions and the mobile culture of trucking. The intent of the project is to bring about a productive collision between the architect's vision of efficient and sustainable housing and the reality of nomadic contemporary lifestyles involving a multiplicity of locations and sites.The viability of prefabricated building solutions was a precondition of modern architecture from the 1920s, expressing the larger societal tendency toward efficient living. But the idea of prefabrication dates back to ancient Rome, at least, and the logical extension of ideas about modular construction has never ceased to percolate in the minds of designers. Likewise, in the early 1960s, the architects who founded Archigram invoked "a new agenda" in which "nomadism is the dominant social force" calling on architects to respond by creating structures that allow for movement and transformation.

The ultimate aim of Truck-A- Tecture is to challenge current definitions of prefabrication and mobile architecture and to expand the horizon of their applications in everyday living to embrace contemporary economic and geographic realities, harking back to what Archigram called an "altered reading of the familiar."
