pavement block making machine multifunctional version | yorkam group

pavement block making machine multifunctional version | yorkam group

A block machine also known as pavement block making machine is used to produce hollow blocks, interlocking blocks, paving blocks, curbstones, porous blocks, solid blocks, insulation blocks, sidewalk blocks, grass planting blocks, stretcher blocks, corner blocks, pillar blocks, jamb blocks, partition blocks, lintel blocks, frogged brick blocks, bull nose blocks, concrete stretcher blocks, concrete corner blocks, solid construction blocks and many others designs. The price of pavement block making machine can vary considerably depending on the model and the manufacturer. The price of the cheapest pavement block making machine is around 1,000 USD. Contact us at +90 505 130 2931 (WhatsApp) and we will be happy to give you valuable information and the price of machine depending on your needs.

Based on production process, we can divide pavement block making machine into two types: mobile type and stationary (fixed) type. Depending on your needs and your request concerning the production process you can choose the machine type.

The mobile type of machine is moving from one place to another while producing the blocks. As the name suggests, a mobile machine makes or in other words lays concrete blocks directly on the ground. This soil (on which the production will be done) must be hard enough to have a very good production.

As you know, the word stationary means fixed. Therefore, the stationary machine cannot move while producing the blocks. It makes or in other words presses the blocks on pallets. The pallets are placed inside the machine. The stationary machine can never make the production of blocks without the pallets.

Based on energy consumption, we can divide pavement block making machine into two types: electric type and diesel engine type. Depending on the availability of energy in your area you can choose the machine type.

Electric type of machine can only work when electricity is available in your area of production. We suggest that you check the availability of electricity before buying such an electrical multifunctional machine. These machines do not consume a lot of electricity.

Diesel engine type of machine can be used in the production areas where electricity is not available. If you dont have electricity available in your area of production this machine is for you. In case of electrical load shedding, electrical power outages, electrical power cut we suggest that you choose a machine with diesel engine.

Hollow blocks, solid blocks, lintel block are some examples of single pattern blocks. To produce these blocks you need only one type of mixed aggregate and commonly do not need color. If you produce only single pattern blocks, then you need a machine with a single mortar hopper.

Pavement blocks or pavers and interlock blocks are some examples of double pattern blocks. When you produce double pattern blocks, you need a machine with a double mortar hopper. These blocks are made of different kinds of mixed aggregate. In many cases you use at least two kinds of mixed aggregate and color as well.

Pavement block machine has many major advantages and benefits such as high production capacity, blocks with good precision and accuracy, best production quality, production on time, aggregate measurement, cement measurement.

A single machine can product more than 10,000 hollow blocks in a single day. The machine can also make more than 600 m2 per day. If you want to produce curbstone the same multifunctional machine can produce more than 3,000 curbs in a day. That is equivalent to 3 kilometers of curbstone in a single day.

It is important to have the same quality for all the blocks. Both hollow blocks and solid blocks are used in the Construction Project. Concrete blocks come in different shape and size. Pavers also come in different sizes and patterns. The machine can produce with precision and accuracy.

You can have a good production quality with the multifunctional machine. One of the major advantages of concrete hollow blocks is their high durability and stability. Concrete hollow blocks are compacted by high pressure and vibration. By this way, the blocks are very strong and able to withstand a high level of loading. They also have high fire resistance and no salinity which reduces their maintenance cost. Compared to other surfacing materials, a good quality block paving is more environmentally sustainable because of its porous nature. This means the paving will absorb rainwater and stop it from gathering on your patio or driveway.

The machine allows you to produce and deliver your blocks on time. On-time delivery makes your customers more pardoning of potential problems. It also starts a conversation with your customers. If a customer knows they can get a product delivered quickly, they are more likely to conduct as much business as possible with your company.

Mostly you need gravel and sand in order to be able to produce hollow blocks, pavement blocks, curbs The multifunctional machine can automatically calculate and mix the quantity of gravel and sand depending on the type of blocks.

For different types of blocks you also need different quantity of cement. A load cell included in the silo of the machine allow you to calculate and mix the cement with the gavel. The process is down automatically through a computer system.

The process of ordering and paying pavement block making machine can be simplified into 7 steps: defining your needs, choosing the moulds, choosing optional spare parts, getting the shipment and delivery price, production time, delivery time, payment.

This is the most important step to consider. You are going to buy the machine not because you want it but only because you NEED it. Therefore, you may want to define clearly your needs regarding the types of blocks you want to produce. Depending on the types of blocks then you can choose the best and maybe the cheapest multifunctional machine that can produce the blocks you want.

The second most important step is to choose the different molds. The machine has a multifunctional working process. That means the machine is able to produce many different types of blocks. But that does not mean the machine came with all the moulds. For every pattern of block, you need one mould. So If you want ten designs of blocks you also need to have ten different molds.

The third most important step is to know and choose the different spare parts and optional parts that could be needed later. When a person is sick he may need to see a doctor and take some medicines. When a machine has an issue it needs spare parts and optional parts. If you buy a multifunction machine without optional spare parts, you will soon or later face some problems. These problem can cause you to delay your production time. Therefore, you may always want to know and buy some optional spare parts.

The forth most important step is to getting the shipment and delivery price. In order to have an accurate budget, you may want to include the shipment and delivery price in your budget. The multifunctional machine is mostly delivered by shipping. The shipping can be calculated by a shipment company and included. You may ask for CIF price or FOB price. The abbreviation CIF stands for cost, insurance and freight, and FOB means free on board. These are terms are used in international trade in relation to shipping, where goods have to be delivered from one destination to another through maritime shipping. The terms are also used for inland and air shipments.

The production or manufacturing time is the number of days in which the machine will be manufactured. The production time can vary depending on the size of the machine you need. The production time can also vary depending on the number of moulds you have chosen. Choosing many molds means a long production time. According to your project you may need to check the production time as well as the delivery time.

The delivery time is the number of days in which the machine will arrive to the port of delivery in your country. If your country is very far from the factory you may face a longer delivery time. Consequently, you may need to manage your project knowing the delivery time. When the multifunction machine arrives to your country, you may pay for customer duties as well.

If you follow all these previous steps, you may be ready to make payment for the multifunction machine. The payment can be made through wire bank transfer from the bank account of the buyer to the bank account of the manufacturer or the seller. Other payment methods are also available. You may ask for accepted payment methods.

These machines became popular and necessary for almost every country. Many entrepreneurs decide to invest in pavement block moulding machine because they know the potential of the construction sector and also their opportunity to make more money with less risk. The demand of concrete hollow blocks or CMU is huge in most of the countries where we have sold our machines. Investing in a manual hollow block machine will be more economical. That will allow you to have best quality concrete hollow blocks compared to the blocks made traditionally.

You can have many pavement block making machine suppliers or manufacturers in Turkey or Europe: Spain, Portugal, Germany As we stated earlier, Turkish block machine are made with good quality and their price is cheaper. Because we already sold many machines we have a rich experience in helping customers to choose the machine depending on their needs and reality.

We dont have any used or second hand pavement block maker machine available right. Of course, you can get a used. These types of used machine do not include a warranty period agreement. Why would you buy a machine without a warranty? Besides, there is no a big difference of price between a new machine and a used one. You may consider making a bank contract to buy a brand new machine. Our advice is to buy a brand new machine if you are looking for a good quality machine for sale.

In order to choose a good quality pavement block making machine, you may consider these three points: the type of steel used in to manufacture the machine, the system of pressure of the machine and the aggregate mixing unit.

The machine mainly made of steel components. It is every time essential to check the type of steel that will be used to manufacture the multifunctional machine. If a good steel is used that means the machine will have with a long lifetime. But if the steel used is of bad quality then the machine could be damaged quickly. The quality of the steel used in some machines makes them last more than 30 years while continuing the production of blocks. We suggest that you check the type of steel used in to manufacture the machine before even buying.

The system of pressure of the machine must be very strong and well built. The quality of the system of pressure define the quality of blocks made. When the pressure system of multifunction machine is not good, the blocks could be cracked easily. This part of the machine continuous exert physical force to the mixed aggregate and for the desired blocks.

The aggregate mixing unit is necessary to mix cement with gravel, sand and water. Then this mixture will be transferred to the multifunction machine for pressure. A concrete mixer (often called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete or mixture for block production.

If you want a good quality pavement block making machine without spending a lot of money in unnecessary equipment, we will be happy to assist you and install your machine. Contact us +90 505 130 2931 (WhatsApp) free call on WhatsApp. We will be pleased to give you good information. We give the price of machine depending on your needs and reality.

The use of blockwork allows structures to be built in the traditional masonry style with layers (or courses) of staggered blocks. Concrete blocks may be produced with hollow centers (cores) to reduce weight or improve insulation. Blockor construction Blockscome in modular sizes, with the most popular typically referred to (by their thickness) as 4-inch, 6-inch, 8-inch, and 12-inch. In the US, CMU blocks are nominally 16 in (410 mm) long and 8 in (200 mm) wide. Their actual dimensions are 38 inch (9.5 mm) less than the nominal dimensions (to allow for 38-inch mortar joints between blocks in any orientation).[ In Ireland and the UK, blocks are usually 440 mm 215 mm 100 mm (17.3 in 8.5 in 3.9 in) excluding mortar joints. In Australia, New Zealand and Canada, blocks are usually 390 mm 190 mm 190 mm (15.4 in 7.5 in 7.5 in) excluding mortar joints.

Construction aggregate, or simply aggregate, is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and roadside edge drains. Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost extender that binds with more expensive cement or asphalt to form concrete.

Gravel is an important commercial product, with a number of applications. Many roadways are surfaced with gravel, especially in rural areas where there is little traffic. Globally, far more roads are surfaced with gravel than with concrete or asphalt; Russia alone has over 400,000 km (250,000 mi) of gravel roads. Both sand and small gravel are also important for the manufacture of concrete.Granularity (also called graininess), the condition of existing in granules or grains, refers to the extent to which a material or system is composed of distinguishable pieces. It can either refer to the extent to which a larger entity is subdivided, or the extent to which groups of smaller indistinguishable entities have joined together to become larger distinguishable entities.A kilometer broken into centimeters has finer granularity than a kilometer broken into meters; whereas, by contrast, molecules of the photographic emulsion may clump together to form distinct noticeable granules, reflecting coarser granularity.

Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. Sand is a non-renewable resource over human timescales, and sand suitable for making concrete is in high demand. Desert sand, although plentiful, is not suitable for concrete. 50 billion tons of beach sand and fossil sand is used each year for construction.The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. The second most common type of sand is calcium carbonate, for example, aragonite, which has mostly been created, over the past half billion years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean.

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is only behind water as the planets most-consumed resource.

Hydraulic cements (e.g., Portland cement) set and become adhesive due to a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in water and safe from chemical attack. This allows setting in wet conditions or under water and further protects the hardened material from chemical attack. The chemical process for hydraulic cement was found by ancient Romans who used volcanic ash (pozzolana) with added lime (calcium oxide).

A material is a substance or mixture of substances that constitutes an object. Materials can be pure or impure, living or non-living matter. Materials can be classified based on their physical and chemical properties, or on their geological origin or biological function. Material science is the study of materials and their applications. Raw materials can be processed in different ways to influence their properties, by purification, shaping or the introduction of other materials. New materials can be produced from raw materials by synthesis.

In its most widely used context, construction covers the processes involved in delivering buildings, infrastructure and industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design, and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning.In general, there are three sectors of construction: buildings, infrastructure and industrial. Building construction is usually further divided into residential and non-residential. Infrastructure, also called heavy civil or heavy engineering, includes large public works, dams, bridges, highways, railways, water or wastewater and utility distribution. Industrial construction includes offshore construction (mainly of energy installations), mining and quarrying, refineries, chemical processing, power generation, mills and manufacturing plants.

Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term masonry can also refer to the units themselves. The common materials of masonry construction are brick, building stone such as marble, granite, and limestone, cast stone, concrete block, glass block, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades.

Building insulation is any object in a building used as insulation for any purpose. While the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation (e.g. for vibrations caused by industrial applications). Often an insulation material will be chosen for its ability to perform several of these functions at once.

Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewerage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering takes place in the public sector from municipal through to national governments, and in the private sector from individual homeowners through to international companies.Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in the understanding of physics and mathematics throughout history. Because civil engineering is a wide-ranging profession, including several specialized sub-disciplines, its history is linked to knowledge of structures, materials science, geography, geology, soils, hydrology, environment, mechanics and other fields.

Concrete masonry units may be formulated with special aggregates to produce specific colors or textures for finish use. Special textures may be produced by splitting a ribbed or solid two-block unit; such factory-produced units are called split-rib or split-face blocks. Blocks may be scored by grooves the width of a mortar joint to simulate different block modules. Hollow blocks and paving blocks are very polular. For example, an 8-by-16-inch (200 mm 410 mm) block may be scored in the middle to simulate 8-by-8-inch (200 mm 200 mm) masonry, with the grooves filled with mortar and struck to match the true joints.

A concrete masonry unit (CMU) is a standard size rectangular block used in building construction. CMUs are some of the most versatile building products available because of the wide variety of appearances that can be achieved using concrete masonry units. Concrete block, when built with integral steel reinforcing or in tandem with concrete columns and tie beams and reinforced with rebar, is a very common building material for the load-bearing walls of buildings, in what is termed concrete block structure (CBS) construction. American suburban houses typically employ a concrete foundation and slab with a concrete block wall on the perimeter. Other common uses for concrete block wall is interior fire-rated partition walls, and exterior backup wall for attachment of building envelope systems and faades.

Rusticated concrete block is the handmade product of in-field advancements in cement making. These concrete blocks first appeared in the late 19th century and are used mainly in residences and small building construction and are meant to resemble rusticated stone blocks. Rusticated concrete block involves a rough surface with a carved bevel detail around the edge of the face of the block. The rough texture of the face is created by running the concrete across a cast-iron face plate or by using a plaster mold taken from a cut stone block.

Compressed earth blocks are made mostly from slightly moistened local soils compressed with a mechanical hydraulic press or manual lever press. A small amount of a cement binder may be added, resulting in a stabilised compressed earth block. For efficient handling and laying, bricks must be small enough and light enough to be picked up by the bricklayer using one hand (leaving the other hand free for the trowel). Bricks are usually laid flat, and as a result, the effective limit on the width of a brick is set by the distance which can conveniently be spanned between the thumb and fingers of one hand, normally about 100 mm (4 in). In most cases, the length of a brick is twice its width plus the width of a mortar joint, about 200 mm (8 in) or slightly more. This allows bricks to be laid bonded in a structure which increases stability and strength

Bricks formed from concrete are usually termed as blocks or concrete masonry unit, and are typically pale grey. They are made from a dry, small aggregate concrete which is formed in steel moulds by vibration and compaction in either an egglayer or static machine. The finished blocks are cured, rather than fired, using low-pressure steam. Concrete bricks and blocks are manufactured in a wide range of shapes, sizes and face treatments a number of which simulate the appearance of clay bricks.Concrete bricks are available in many colours and as an engineering brick made with sulfate-resisting Portland cement or equivalent. When made with adequate amount of cement they are suitable for harsh environments such as wet conditions and retaining walls. They are made to standards BS 6073, EN 771-3 or ASTM C55. Concrete bricks contract or shrink so they need movement joints every 5 to 6 metres, but are similar to other bricks of similar density in thermal and sound resistance and fire resistance.

Concrete blocks are made from cast concrete (e.g. Portland cement and aggregate, usually sand and fine gravel, for high-density blocks). Lower density blocks may use industrial wastes, such as fly ash or bottom ash, as an aggregate. Recycled materials, such as post-consumer glass, slag cement, or recycled aggregate, are often used in the composition of the blocks. Use of recycled materials within blocks can create different appearances in the block, such as a terrazzo finish, and may help the finished structure earn LEED certification. Lightweight blocks can also be produced using autoclaved aerated concrete.

The American Society for Testing and Materials publishes an exhaustive listing of specifications including ASTM D 692 and ASTM D 1073 for various construction aggregate products, which, by their individual design, are suitable for specific construction purposes. These products include specific types of coarse and fine aggregate designed for such uses as additives to asphalt and concrete mixes, as well as other construction uses. State transportation departments further refine aggregate material specifications in order to tailor aggregate use to the needs and available supply in their particular locations.Sources for these basic materials can be grouped into three main areas: Mining of mineral aggregate deposits, including sand, gravel, and stone; use of waste slag from the manufacture of iron and steel; and recycling of concrete, which is itself chiefly manufactured from mineral aggregates. In addition, there are some (minor) materials that are used as specialty lightweight aggregates: clay, pumice, perlite, and vermiculite.

The advent of modern blasting methods enabled the development of quarries, which are now used throughout the world, wherever competent bedrock deposits of aggregate quality exist. In many places, good limestone, granite, marble or other quality stone bedrock deposits do not exist. In these areas, natural sand and gravel are mined for use as aggregate. Where neither stone, nor sand and gravel, are available, construction demand is usually satisfied by shipping in aggregate by rail, barge or truck. Additionally, demand for aggregates can be partially satisfied through the use of slag and recycled concrete. However, the available tonnages and lesser quality of these materials prevent them from being a viable replacement for mined aggregates on a large scale.

The largest-volume of recycled material used as construction aggregate is blast furnace and steel furnace slag. Blast furnace slag is either air-cooled (slow cooling in the open) or granulated (formed by quenching molten slag in water to form sand-sized glass-like particles). If the granulated blast furnace slag accesses free lime during hydration, it develops strong hydraulic cementitious properties and can partly substitute for portland cement in concrete. Steel furnace slag is also air-cooled.

Heavy equipment or heavy machinery refers to heavy-duty vehicles, specially designed for executing construction tasks, most frequently ones involving earthwork operations or other large construction tasks. Heavy equipment usually comprises five equipment systems: implementation, traction, structure, power train, control and information.
