Autoclaved aerated concrete blcok plant /AAC block plant

AAC block plant Introduction

Autoclaved aerated concrete (AAC) is the light and porous buidling material. It has light weight keeping temperature cant burn and other advantages. Autoclaved aerated concrete can be made into many kinds of bricks (for example:600×200×100,80×80×180,240×115×53,600×200×125),they could be used industry building and common building.they are more and more popular in the world.in the future,they will replace the Clay brick completely.

AAC block plant common conception

Common concrete density is usually 1600-2400kg/m3,but Areated aerated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain,main use silicon material (for example:coal ash,sand,stone dust and others ),through making the material small for example sand,they can be used directly if has enough degree of small (for example coal ash.Mixing calcium material lime cement water to a special slop,then add the aluminum dust and the additive.Make the aluminum dust and (Areated aerated concrete)the special slop have a Chemical reflect.then produce Hydrogen to make the concrete slop to expanding or swell,foam.Next,put them into the curing room to concreting cutting steaming curing,last,there will bacome the light brick,the porous rate is 70-80%.

AAC block plant Autoclave

Autoclave is the key equipment in the production of aerated concrete and autoclaved brick. Our autoclave is a horizontal cylindrical device made of steel. The quality of the autoclave is good, and its performance is reliable.

Purpose of the Autoclave :The autoclave is used for curing the cut body under high temperature and high pressure.

Structural Features of Autoclave :Our autoclave is a horizontal cylindrical device made of steel. Its cover is made of a whole piece of pressed 16 M nR steel board, and the flanges of cover and body adopt a whole piece of forged and processed 16 Mn steel board. The welding lines of pressed components are subjected to heat treatment and strict nondestructive test. The maximum design pressure reaches 1.65 Mpa.

Ball Mill of AAC block Plant

Ball mill is an efficient tool for grinding many materials into fine powder. Thereare two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of dischargingmaterial.

Jaw crusher of AAC block plant

Cutting machine is the main and key equipment in the production of aerated concrete with annual output of more than 50,000m3 . This equipment is absolutely necessary for promoting the output and quality of AAC.

Casting Machine of AAC block plant

Aerated concrete casting machine is the main equipment in the production of aerated concrete. It is mainly used for mixing the slurry, cement, quicklime, gypsum, and liquid of aluminum paste according to certain proportion in order to make them evenly mixed and react with each other adequately. Then the mixed slurry is poured into the mould frame in due time by the machine.

Purpose of the Casting Machine :Casting machine is used for mixing the raw materials to make them evenly mixed and react with each other adequately, then pours the materials into the mould frame in due time.

Structural Feature of the Casting Machine :The aerated concrete casting machine adopts screw-propeller mix, and strong whirlpool is formed in the tank so that the envelope of quicklime is damaged, as a result, the materials can be mixed adequately. Meanwhile, the height of the casting machine arm, which can go up and down , can be adjusted in the casting process to avoid splash. Two types of the machine is available: the mobile type and the stationary type. And quantitative moulding can be achieved by both of them.

Cutting Machine of AAC block plant

Cutting machine is the main and key equipment in the production of aerated concrete with annual output of more than 50,000m3 . This equipment is absolutely necessary for promoting the output and quality of AAC.

Working Theory of the Aerated Concrete Cutting Machine :The aerated concrete block and the bottom plate are put onto the overturn table and moved to the slip table of cutting machine, then they are turned by 90°, and the block is moved to the destination. The block is cut in four sides horizontally, and then cut in two sides vertically. The block moves from the small slip table to overturn table, and is turned by 90° so that it is put on the overturn table. The whole process is automatic.

Purpose of the Aerated Concrete Cutting Machine :The cutting machine is used for cutting the aerated concrete block, which has been hardened and released from the mould.

Features of the Aerated Concrete Cutting Machine

The cutting machine can cut the block horizontally and vertically in one step;
The cutting machine can accomplish six-side cutting, and the precision reaches the standard of GB/T11969 - 1997;
The technology of the cutting machine is advanced, and there is no need for secondary crane, which reduces the abrasion of the block arising from multiple cranes;
The cutting machine peels the block in six sides. The waste materials, instead getting into the autoclave, can be retrieved and used again.
The structure of the machine is compact, the operation is easy, and the maintenance is simple;
The whole cutting process is accomplished automatically.

AAC hoist of AAC block plant

Hoist is the main ancillary equipment in the production of aerated concrete. Hoist lifts the body, which has been released from mould frame, and puts it on the overturn table. Then the body can be cut.

AAC mould of AAC block plant

Mould is the main ancillary equipment in the production of aerated concrete. The casting machine pours the well-proportioned and mixed materials into the mould. After foaming, hardening, and released from the mould frame the block can be cut.

Steam-curing Cart of AAC block plant

Steam-curing Cart is the main ancillary equipment in the production of aerated concrete. After cut the block was hoisted into the steam-curing cart together with the bottom plate. The carts with the blocks and the bottom plates are put into the autoclave in groups for steam curing.

AAC block plant Advantages

light weight

Areated concrete density is usually 400-700kg/m3,(according the market in produce ),same as 1/3 of clay brick and 1/5 common concrete.So use the Autoclaved aerated concrete can reduce the weight of the build more,and also reduce the beam of roof and pillar press best.then you can see,it can save the material and cost,it also fighting shaking.

keeping temperature

It has many porous,the delivery hearting coefficient is 0.9-0.22W/(mk),the same as 1/4 or 1/5 of clay brick,so Autoclaved aerated concrete is best materials now in the world. Also many kinds raw material,have lowest wasteMain Material:coal ash sand waste mine material coal stone,stone dust and other silicon materials.
