Introduction of AAC Block Production Line:
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.
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.
