Jaw crusher is traditional crushing equipment mainly used for primary crushing. Jaw crusher is also called primary jaw crusher and stone jaw crusher, which has always been broadly applied in industrial production due to its simple structure.

Moreover, it has long been widely used for the coarse, medium and fine crushing of various kinds of ores and rocks like limestone,pebble and granite whose compression strength is 147~245MPa in many industrial departments such as metallurgy, chemistry, building material, power plant and transportation. The maximum compression strength of the materials to be crushed is 320MPa.

Jaw crushers can be classified into four models, namelyPE jaw crusher, PEX jaw crusher, HD jaw crusher and CJ jaw crusher and mobile jaw crusher according to Different technologies and configurations. Different models with different price. The pe jaw crusher price is lower than other jaw crusher with same configuration. But low price does not mean cost-effective, compared with the other three models, CJ jaw crushers with fewer spare parts, wedge block discharge adjustment, light-weight toggle plate, integrated motor seat and steel base enjoy the most cost-effective. PEX jaw crusher as second broken equipment is more inexpensive than other second crushing machine such as impact crusher and cone crusher. HD jaw crusher is cheaper than CJ jaw crusher and it is more efficient than PE jaw crusher. Mobility is the most significant characteristic and advantage of mobile jaw crushers. And the mobile jaw crusher price is highest because if was equipped with feeders and other related equipment.

According to size of feed port, the jaw crushers can be classified into small (mini) jaw crusher, middle-sized jaw crusher, Large jaw crusher; the smallest feed port of jaw crusher is 200*300 mm (pe) and the largest feed port is 1600 mm*2100 mm and its production capacity can up to 1300-2200t/h.

As jaw crusher is the oldest crushing equipment, there are thousands of manufacturers around the world. Finding out the right one from numerous jaw crusher manufacturers is still a significant challenge in a number of jaw crusher users. Actually our users need the right one not the expensive one. Therefore when we choose the manufacturers, we should pay attention to many aspects such as: production quality control, manufacturers strength, after-sales service, spare parts supply, warranty period, operation training and so on.

primary crusher selection & design

primary crusher selection & design

The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6. Wet, sticky and extremely hard or tough feeds will tend to reduce crusher capacities.

Selectiingwhat size a crusher needs to be is based on factors such as the F80 size of the rocks to be crushed, the production rate, and the P80 desired product output size. Primary crushers with crush run-of-mine rock from blast product size to what can be carried by the discharge conveyor or fit/math the downstream process.A typical example of primary crushing is reducing top-size from 900 to 200 mm.

Ultimately, the mining sequence will certainly impact the primary crusher selection. Where you will mine ore and where from, is a deciding factor not so much for picking between a jaw or gyratory crusher but its mobility level.

The mom and dad of primary crushers are jaw and gyratory crushers. In open-pit mines where high tonnage is required, thegyratory crushers are typically the choice as jaw crushers will not crush over 500 TPH with great ease. There are exceptions like MPI Mineral Park in AZ where 50,000 TPD was processed via 2 early century vintage jaw crushers of a:

The rated capacity at 5 closed-side setting was 490 stph based on standard 100lbs/ft3 feed material. These crushers were fed a very fine ore over a 4 grizzly which allowed the 1000 TPH the SAG mills needed.

In under-ground crushing plants where the diameter of the mine-shaft a skip forces limits on rock size, a jaw crusher will be the machine of choice. Again, if crushing on surface, both styles of stone crushing machines should be evaluated.

should know all about stone crusher plant - machine thug

should know all about stone crusher plant - machine thug

In the market, various kind of crusher plant is there and used in different industries for fulfilling the crushing needs but here we will talk all about the stone crusher plant. How stone crusher plant is working, what are the stone crusher machine is available in the market. Types of stone crusher plant available and kind of requirement plant fulfilled.

Earlier crushing plant is one-stop installation activities but nowadays as requirement changes, stone crusher plant technology, design, input, output, capacity changed. International brands continuously updating their product with technology, digitization, and artificial intelligence.

Stone crushing industry engaged in producing a crushed stone that used as a raw material for infrastructure projects like, road, highway, bridges, building canals, etc. All projects are considered as the core infrastructure work that gives the economy boom.

Stone crusher units are not alone. Along with these plants, stone mining also associated. In fact, stone mining is the primary activity, and the crushing plant is the secondary activity that can be considered.

The stone crusher plant will available from 50 TPH to 600 TPH (ton per hour). The plant can produce the 8 variants of material. Just to get the different variant material you also need to put the screening plant that just separates the different materials according to client or market demand.

Raw Material processed through the vibrating feeder to crusher gradually and crusher crushed the material into respective pieces. From Crusher material conveyed to belt conveyor for secondary crushing before went on vibrating screen plant. Vibrating screen plant separates the quality and qualified material to final products.

And unqualified material carried back to stone crusher and reprocesses it. Then again material went through the above process. The customer gets the required material according to the standard quality and different sizes.

To get the fine product from the crusher. We need to pass it through three types of crushers in stage-wise. First Primary Crusher in that direct material comes from mines. Secondary crusher process the primary crusher material that already crushed at material size reduced and tertiary crusher which reduces the material size further. The manufacturer gets the desired size. That can be further supply to users.

A jaw crusher is the compression kind of crusher and used for crushing rock between two heavy steel jaws. The movable jaw compresses the material against the fixed jaw and crushes material at the desired size. Material exits from the bottom of jaws.

Double toggle jaw crusher is heavier and lots of moving parts than the single toggle jaw crusher. The main difference is the position of eccentric between both of them. Jaw crusher available in three variant mobile, stationary, and portable design whatever customer suits and full fills there need may consider it.

Cone Crusher also called a gyratory crusher. Cone crusher also a compression kind of machine that reduces, squeezing, or compressing the material between a moving piece of steel and a stationary piece of steel. The material passed it through the bottom of the machine after passed the cavity.

The material gets in the feeder from the upper side and material output from the bottom. Cone crusher generally delivers the material 4:1 or 6:1 ratio. The below picture will clear more you about the Cone crusher.

It consists the two opposite direction driven cylinders that mounted on horizontal shafts. The gap between the both cylinders can be adjusted according to desired results. Generally both cylinders cover with the manganese steel liners.

There is two kinds of roller crusher 1, Double roll crusher. 2, Single roll crusher. Name itself clears you both work. In double roller two cylinders are set up while in single roller crusher only has a cylinder that move at one place attached with horizontal shaft and material grind between the cylinder and inside body.

Impact crusher is process the material by compression & force between two surfaces towards one another to crush the material caught between them. Material contain in the chamber that open according to desired result from bottom.

Vertical Shaft Impact Crusher is generally used in the last phase. VSI looks like a cone crusher from outside but working style different in both of them. In vertical shaft crusher, shaft putted in vertical way.

Production Requirement What actually production requirement you have. Many a time companies setup the plant especially for specific projects only. So you need to consider your whole project requirement.

Ore Characteristics Material you want to crush or output you want. That really impacts your decision like if you need the fine product then you may go for the roller crusher. So according to need of material you need to setup the plant.

Operational Considerations Operational consideration means you might have constraint in operation like location. Location might be the operational constraint or labour constraint. Plant may near to your mining that reduce your transpiration cost but you may not allow doing so.

jaw crusher | primary crusher in mining & aggregate - jxsc mine

jaw crusher | primary crusher in mining & aggregate - jxsc mine

Product Introduction JXSC jaw type rock crusher is usually used as a primary crusher and secondary crusher to reduce the size of medium-hard materials to smaller physical size. Jaw rock crushers are capable of working with the mobile crushing station, underground crushing because of its related small volume. Capacity: 1-1120TPH Max Feeding Size: 120-1200mm Application Mining, metallurgy, building materials, quarrying, gravel & sand making, aggregate processing, recycling, road and railway construction and chemical industry, etc. Suitable Material Granite, marble,basalt, limestone, coal, quartz, pebble, iron ore, copper ore, etc.

40 years of manufacturing and engineering experience keep us innovative and knowledge in the rock break machines and its applications, which thus provide reliable industry rocks crushers and solutions for every customer using jaw crusher manufacturers JXSC machines to meet their production goals. The jaw crusher machine family consists of different sized models that are designed to bring maximum output with minimum cost. Some workplaces have limited conditions and are unable to provide electricity or are underpowered. According to these conditions, JXSC specially designed diesel jaw crusher. The diesel-jaw crusher is actually with electric, but the original jaw crusher was added with a diesel engine equipment that a dual-purpose crusher.

JXSC the crushers machine with a non-welded frame has been proved that it has outstanding solid and durable strength. All the alloy casting frame components turn out that with premium quality, wear-resistant property.

The design of pitman and long stoke improves productivity and reduction. A wider feeding material opening increases the volume of insulating material and makes the ore material entering the crushers crushing chamber smoothly. A sharp angle makes the materials flow down speed faster and reduces the wear cost. Besides, the strike force could be stronger thus increase the production efficiency as well as the reduction ratio.

Types of jaw crushers: on the basis of the stone break equipment size and capacity can divide into a heavy and small(mini) portable jaw rock crushers. According to the working principle can be split into single toggle and double toggle jaw rock crushers machine.

A series of jaw stone crushers use compressive and squeezing force for reducing materials. This physical force is created by the two jaw plates, one of which is a movable plate and another is fixed, both of them are made of manganese. A V-shaped cavity, crushing chamber, is formed and the hydraulic discharge gap width of the crushing chamber, we can determine the suited feeding material size and discharging size, the width of top feeding is larger than that of bottom discharging.

Jaw crusher is a heavy-duty machine that crushes hard materials. So its hence muse be robustly constructed. Crusher frame is made from steel or cast iron. The jaws are made of cast steel. The liners are made fromNi-hard, Ni-Cr alloyed cast iron or manganese steel which can replaceable and use to reduce frame wear. The cheek plates are also made from hard alloy steel and installed to the sides of the crushing chamber to protect the frame from wear.

The jaws can be made in smooth or corrugated, but often corrugated. Because the latter crushing the hard and abrasive ores is better. The angle between the jaws is usually less than 26. This is because a large angle will cause the particle to slip which non-crush.

It uses curved plates to avoid the near the discharge of jaw crusher blocking. The bottom of the swinging jaw is concave, and the relative lower part of the fixed jaw is convex. The materials reduction in size when nears the exit. So the material is distributed over a larger area, and the jaws plates wear less.

The type of crushed materials determines how to design the max amplitude of swing of the jaw and the amplitude adjusted by changing the eccentric. The length from 1 to 7 cm depends on the crusher machine size. Jaw crushers are supplied in sizes up to 1,600 mm (gape)1,900 mm (width). For coarse crushing application (closed set~300 mm), capacities range up to 1200 tph.

Jaw crusher parts must have some wear after a period of use, but the easily damaged parts will wear out more. The price of crushing equipment with the same specifications and handling capacity is different in the material of parts.

Guard Plate The guard plate is made of high-quality high manganese steel, which is located between the fixed plate and the movable plate. The whole body is mainly to protect the jaw crusher frame wall.

Toothed Plate Tooth plate is divided into movable and fixed tooth plate, but both is made from high manganese steel casting. In order to prolong its service life, its shape is designed to be symmetrical. That is when one end of the wear can be used to turn the head. The movable and the fixed teeth plate are the main parts for stone crushing. So the movable teeth plate is installed on the movable jaw to protect the movable jaw.

Toggle Plate The toggle plate is a cast iron piece that has been precisely calculated. It is not only a force transmission component but also the safety parts of the crusher. When the crusher falls into the non-crushing material and makes the machine beyond the normal load, the toggle plate will immediately break. Then the crusher machine stops operation, thus avoiding the damage of the whole machine. The toggle plate and the toggle plate spacer adopt the rolling contact model which less attrition under normal use. It just needs smear a layer of grease on the contact surface is ok.

Triangular Belt When the motor transmits power, the triangle belt is connected with the pulley and the grooved pulley of the motor to drive the eccentric shaft and make the moving jaw move back and forth according to the predetermined track.

The tooth plate of the most jaw crushers are made of manganese steel, bearing linings are made of babbitt alloy, sliding blocks are made of carbon steel, toggle plates are made of cast iron, springs are made of 60SiMn. Regular Inspection and maintenance of the machine can extend its service life. In order to reduce customer costs, we will generally be in the purchase of customers are advised to buy some spare parts. Because once the parts need to be replaced, the temporary purchase will take some time. The wait time may cause the entire breakage line to suspend operations, thereby increasing operating costs.

In short, the jaw stone crushers are mainly used for primary crusher, the crushing stone is relatively large. The types of crusher machine's chamber are deep and no dead zone. It improves that the feeding capacity and output. The crushing ratio is large and the product particle size is even. Shim type outlet adjustment device, reliable and convenient, large hydraulic adjustment range that increased the flexibility of the equipment. Simple structure, reliable work and low operation cost. The adjustment range of hydraulic discharge opening is large, which can meet the requirements of different users, low noise and less dust.

Impact crusher for crushing medium-hard stones, and mostly used for secondary crusher. The impact crushers have a big feeding port, high crushing cavity, high material hardness, big block size and little stone powder. Convenient maintenance, economic and reliable, high comprehensive benefit.

There are many ways to crush a rockand depending on your industry, your location, and the project specifications, the equipment that you use and the layout by which it crushes that rock is often rather unique, especially when it comes to product size.

The degree to which material is reduced through stages of primary, secondary, and tertiary crushing can depend on the type of material, like aggregate, concrete, and asphalt, and can also depend on the variety of output sizes needing produced.

Primary crushing is the first stage of material reduction and can sometimes be the only stage needed to generate the desired product for a job. Depending on the setup, primary crushing will take the larger material that has been blasted, excavated, or reclaimed and process it through an impactor, jaw, or gyratory crusher to generate a range of product sizes.

For many aggregate producers, utilizing a closed-circuit portable crusher plant with scalping and screening capabilities can be all they need to create the product they need. But when a wider variety of product is desired and certain material is being processed, like concrete and asphalt, it can be valuable to rely on additional stages of crushing, like secondary and tertiary.

Secondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is effective at breaking down these types of material.

There are also tertiary and even quaternary stages of crushing that exist to achieve the finer levels of material reduction. These stages in addition to secondary crushing can often be laid out utilizing an open-circuit portable crusher plant system where processed material is screened and conveyed from one crusher to the next.

Relying on these many stages of crushing beyond only primary can add great value to a crushing operation. Not only can multiple sizes of product be generated, but often in an open-circuit crushing layout, the flow and processing of material is streamlined and can increase output when compared to a closed-circuit crushing layout.

Eagle Crusher offers a comprehensive portfolio of closed-circuit and open-circuit portable crusher plants alike, manufacturing powerful equipment like horizontal-shaft impactors, jaw crushers, and cone crushers that are critical for any stage of crushing. When you speak with a Team Eagle representative, we can help you determine which crushing equipment will be best for your next project.
