AAC Block are made of flyash (limeslag or sand) as main raw material,cement and lime as cementing materials,and aluminum powder as foaming agent.The main forming procedures are Material crushing,measuring,mixing,pouring,curing,cutting and steaming.As a new wall body material with the characteristics of light weight, heat preservation,energy saving,waste recycling, environmental protection and convenience etc,AAC Light-weight block is now emphatically promoted by the world.

First,Material Handling 
Jaw Crusher 
    Mainly used for compressive strength less than 320 MPa materials, with big crushing ratio, high yield, even gra- nularity, simple structure, reliable operation, easy maintenance, low operating cost. The crusher has been widely used in mining, smelting, building material, highway, railway, water conservancy and other departments. Work principle of Jaw crusher: When jaw crusher works, the motor through the belts driven eccentric shaft rotation, so that the movable jaw cycle close, leaving the fixed jaw, multiple break materials through squeeze, rub, grind the materials, then make the material into small whereabouts, until discharged from the discharge door.
Ball Grinder
    Ball grinder is used to grind a variety of ores and other mate- rials in the mineral processing, building materials and chemical industry. It can be divided into wet and dry two grinding types. According to the ways of discharging, it also can be divided into grid and overflow type.

Beating Pool
    Pouring materials into pool and modulated into slurry.

Silo
    Used for storing the Cement,Lime and other powder material, the effective volume are 100m³,200m³,300m³.


Second, Dosing And Pouring
Measure
    Measuring system is used to weigh each raw material.
Pouring Mixer
    The casting mixer for mixing the slurry,powder,other materials and the aluminite suspended particles after being metered, then open the discharging valve, pouring the materials into the mould then send the products in the precuring room.
Mould
    Slurry could be held in the combining of mould and side plate. After curing it would be solidified into the semi-finished pro- duct. Mould size:4.2m,6m.
Side Plate
    The side plate is used to load the semi-finished product which will be cut by cutting machine and fed into the au- toclave to be hardened together with the trolley.
Curing Room
    After pouring,use conveyor chain push mould into curing room under temperature 50-70 degrees. The curing time would be 1.5-2 hours.(according to favorable geographical condition, the step can be skipped.)
Third,Tilting Cutter
Turning Crane 
   Lift the poured and cured product together with mould and side plate up in the air, turn it over 90 degrees to keep the block upright, carry it to the cutting cart, open mould and lift away the mould so that the semi-finished product can be out. Then mount and clamp the side plate on the mould once again, turn it over 90 degrees and carry it back to the starting line so that pouring can be resumed.
Cutting Machine
    Operating principle: Using turning crane to turn the roughcast with 90 degree, left the roughcast with side plate on cutting cart after demoulding. Motor driven cutting cart move to length cutting device to process length cutting,groove milling,and horizontal cutting; Then the cutting cart move to the center of transverse cutting device, the transverse frame perform transverse cutting from up to down vertically. Afterwards the turning and grouping crane carry the roughcast(with side plank) to curing cart and the cutting cart return back to original position to have next movement.
Turning & Grouping Crane
    After cutting, using the crane send the semi-finished products to the curing cart and grouping crane.
Curing Cart
  Curing cart is used for carrying the product with side plate pass in and out of autoclave. The cut product is hanged with side plate to steam trolley and be carried into autoclave for curing.
Fourth,Finished-Product Out From Autoclave 
Block Clamping Machine
    Carry the finished-product to packing line for making final package after autoclaved
Separator
    The separator is used to separate the plaster block into pieces, in order to be transferred and used.
Autoclave
    Autoclave is a large pressure vessels used for steaming aerated concrete, sand-lime, fly ash brick or standard brick,the autoclave complete the hydrothermal reaction of CaO-SiO2-H2O. It is also widely used for other required pressure steam curing of the production project. Such as high-strength gypsum, insulation materials, rubber, high-strength glass, cement, pipe piles and timber, pharmaceutical, chemical and other industries. According to user requirements, our company can also design and manufacture of various forms of autoclave in order to meet the needs of the user a variety of purposes.
