Capacity:

from 50000 cubic meter to 300,000 cubic meters per year.

AAC Processing Technics:

1. Storing and supplying of raw materials of AAC blocks.

All raw materials are carried into factory by trucks. Fly ash, sand or lime are gathered in specified raw materials field waiting for using. Sacks of cement and bulk cements stored in cement warehouse. Chemicals and aluminum powder are separately kept in chemical warehouse and aluminum warehouse. When used, these raw materials are carried into workshop respectively.

2.Processing of raw materials:

Quick lime is sent by vibrating feeder and belt conveyor into jaw crushers to smash. Smashed lime is sent into lime silo by bucket elevator and then is transported into ball mills by screw conveyer. Fined materials are sent into proportion bin by screw conveyer and bucket elevator. Aluminium powder is lifted by a truss motor to second layer of batch planta and empty into mixer.Then quota water is poured to make aluminium powder into suspension.

3.Aerated block Ingredients,Stiring and Casting

Fly ash (or sand or stone powder ) and waste slurry are measured in measuring tank. After the measuring and mould in their place, slurry stirring begins. Slurry temperature should reach about 40°-This is technical requirements. If the actual temperature doesn’t arrive 40°,vapor is used in the measuring tank to raise temperature. Half or one minutes before casting, aluminium suspension is supposed to be added to the slurry.

4,Pre-curing and Cutting Process

Cut model is conveyed to pre-curing room for gas forming. Room temperature should range from 50°to 70°.This period lasts one hour and a half to two hours. (If materials take on geographical advantages, this pre-curing can be eliminated). Pre-cured green body together with mould frame will be lifted to cutting station that is covered by autoclave board. After frame detachment, cutting machine do cross-cutting, vertical cutting, face-milling and tip-binding. At the same time, die grid is hanged to pre-curing cart for manual cleaning and degreasing to prepare for the next perfusion. The cutting ready embryo are carried to pre-curing cart together with die seat, palletizing in two tiers, four pillars between two the tiers, and get into grouping process. When the cutting of body is completed, partial waste materials cut down will be processed into waste material slurry which then will be pumped to the slurry tank located at the topmost story of batching building, after that, add the necessary raw material, then transported into a pulping machine for reuse.

5, Autoclave and End-products

After the green body is grouped, open autoclave door, a hoist will draw out autoclave cart; Put all green body on the cart and wind the cart back into the autoclave for steaming. Finished products will be carried by a bridge crane to a stockyard, then to a products dump by fork lorry load. The empty card together with autoclave bottom is lifted to return-line cart and winched back for another circle.
