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.

Advantages of AAC

light weight : The dry weight of AAC block is 400-700kg / m³, which is only 28% of clay
brick , and 20% of concrete block, reducing the weight of the building.

Convenient and fast construction:

the volume of one AAC block
equal to 18 pieces clay
bricks, can greatly improve the speed of construction. Can be easily sawing, drilling,
nailing, hanging, engraving, which makes pipelines laying, re-decoration more simple.

Exact dimensions:

Product dimensions precise,making the tolerance
of length, width and
height can be controlled within ±1.0mm. These precise size makes mortar layer thinner
and reduce the cracking problem.

Fire retardant:

AAC block is a non-combustible inorganic material
with excellent fire
resistance, fire resistance is more than 700℃. Fire resistance of AAC block wall (200mm
thick) can up to 8 hours, which is the first grade refractories.

Production process Description

Raw material processing

1. The cement is bulk cement, which is pneumatically transported to the cement storage bin bya bulk cement truck. The cement storage capacity considered in this design is 90t.
2. After the lime and gypsum are crushed by the jaw crusher by calculation, the elevatorenters the storage bin, is fed by electromagnetic vibration, enters the mill, and the finely mixed ash is transported by the elevator to the ash storage bin for backup.
3. The sand is transported into the slurry storage tank through ball milling and water wet milling into a slurry storage tank, and after the slurry specific gravity required for production is reached, it is pumped to a stirring pouring machine through a slurry pump.

Ingredients pouring

After the materials are ready, measure them separately, mix and stir with a stirring pouring machine,
add the metered and stirred aluminum powder suspension, stir for 30-45 seconds, and then pour into the mold.

Cutting Section.

After pouring and foaming, the green body is statically stopped to a certain hardness (about 1.2-2h), that is, cutting is performed, and the green body is lifted to a steaming cart by a marshalling spreader, and then marled into a kettle.

Autoclave

After cutting the green bodies, they can be marshalled to a certain number by driving and then enter
the autoclave for autoclaving.
