Introduction of AAC Block Production Line:
1. Storing and supplying of raw materials of AAC blocks:
All raw materials are carried into factory by trucks, such as Fly ash, sand or lime are gathered in specified raw materials field waiting for use. Sacks of cement and bulk cements stored in cement warehouse. Chemicals and aluminium powder are separately keeped in chemical warehouse and aluminium ware hours.When used, these raw materials are carried into workshop respectively.
2. Processing of raw materials:
Fly ash, sand or limestone is sent into ball mills by vibration feeders and belt conveyor.Then fine powders of flyash,sand or lime are pumped into slurry tank.
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 conveyor. Fined materials are sent into proportion bin by screw conveyor and bucket elevator.
3. Aerated block ingredients,stiring and casting
Flyash (or sand or stone powder )and waste slurrry are measured in measuring tank.After the measuring and mould in their place,slurry stirring begins. Slurry temperature should reach about 40°c.
4. Aerated block’s procuring and cutting.

Introducing the domestic and international advanced technology, the manufactured autoclave aerated concrete (AAC)is divided into ground flip (hydraulic flip) cutting machine, overhead flip (YiTong type mechanical flip) cutting machine according to different cutting process, which can produce aerated concrete block and boards with not more than 6 M length.
Provide the complete set of production line shared by the aerated concrete block and limesand brick, applicable for the annual output of 100000 + 100000 cubic meters
Provide the complete set of production line of the sand aerated concrete blocks and boards, applicable for the annual output of 50000 -200000 cubic meters
Provide the complete set of production line of fly-ash aerated concrete blocks and boards, applicable for the annual output of 50000 -200000 cubic meters
Autoclave aerated concrete block is a porous concrete product, using sand(or fly ash), cement, lime, aluminum (or aluminum paste), gypsum and othermaterials, through grinding, measuring, mixing,pouring, curing, cutting, autoclave and other processes, it belongs to silicate concrete. It is known as autoclave aerated concrete, but generally referred to AAC. It is mainly used for the frame structure building, inner wall partition, external walls orinsulation composite wall.
