Raw materials of Aerated Autocalved Concete coal fly ash or lag or sand.Cement and lime is cementing materials,Aluminium is foaming agent.After crushing,measuring,mixing,pouring,steaming,cutting and autoclave,it become aerated concrete.AAC Blocks is a type of new walling materials,it have advantages of light weight,heat preservation, heat insulation, energy saving, waste utilization and easy construction.It is environmental protection projects promoted by all countries.

Process Flow

Applications

Large piece of Lime Stone is crushed by Jaw crusher firstly.Bucket lifting machine transport small piece lime stones into Raymond mill,which mill small lime stones to be lime powder.Then bucket lifting machine transport lime power into lime silo for storage.

Coal Fly ash or sand slurry is mixed and stored in the slurry tank.

Lime powder and cement is transported by screw conveyor and measured by Powder Weighing Tank one by one.
Coal fly ash slurry or sand slurry is pumped and measured by slurry weighing tank on by one.

Lime powder,cement,coal fly ash or sand slurry is sent to Mixing tank together.Aluminum is mixed by Aluminum mixing tank and pour into mixing tank.All raw materials will be mixed in mixing tank.

Shuttle Cart transport mould under Slurry Mixer and ready mixed slurry is poured into mould.

Mould filled with slurry will stay in curing room for curing.

Crane turning machine put ready block onto cutting machine.

Cutting machine take ready block to lateral cutter and vertical cutter for cutting.

The blocks is put on steaming trolley by hanger.Each trolley have two package of blocks.It is six steaming trolleys for each autoclave.The trolley is pulled by winch.

Coal Boiler is for supplying heat and steam for autoclave and curing room.

Blocks will be steamed about 8 hours inside autoclave.After ready blocks is taken away,steaming trolley and plate is transported back for recycle.
