What is AAC Block?
Raw Materials: AAC Block (Autoclaved Aerated Concrete Block) is made from key materials including sand, cement, gypsum, lime, and aluminum paste.โ
Production Processes: It undergoes professional procedures: batching, mixing, pouring, aerating, static pre-curing, cutting, and high-temperature high-pressure autoclaving.โ
Core Feature: The aeration process creates numerous uniform tiny pores inside the block.โ
Key Advantages: Offers light weight, high strength, thermal insulation, soundproofing, and excellent fire resistance.โ
Applications: Widely used in wall masonry and structural work for civil, commercial, and industrial buildings.โ

Machines used in AAC Block manufacturing
1. Jaw Crusher
Perform preliminary crushing on bulk raw materials (e.g., lime, gypsum), breaking large-particle raw materials into sizes meeting subsequent processing requirements to lay the foundation for grinding and homogenization.โ
2. Ball Mill
Finely grind the crushed siliceous raw materials (sand, fly ash) and calcareous raw materials (lime) to make the raw materials meet the specified fineness standards and ensure sufficient subsequent batching reactions.
3. Vibrating Screen
Screen the ground raw materials to remove unqualified coarse particle impurities and ensure that the particle size of the raw materials entering the batching link meets the process requirements.
4. Screw Conveyor / Bucket Elevator
Transport various processed raw materials (sand, cement, lime, etc.) from the storage bin to the batching system to realize automatic transfer of raw materials.
5. Forced Mixer
Fully mix the measured raw materials with water and aluminum powder foaming agent to form a uniform slurry, providing a stable material foundation for subsequent pouring and foaming.
6. Pouring Machine
Uniformly pour the mixed slurry into the mold to ensure that the slurry is distributed flatly in the mold and create conditions for the foaming and forming of the blank.
7. Pre-curing room
Provide a constant temperature and humidity static environment for the poured mold, allowing the slurry to complete the foaming reaction and initial setting process and form a blank with a certain strength.
8. Mold
Serve as a carrier for slurry foaming and blank forming, determining the initial shape and size of the blank.
9. Turnover Demolding Machine
Separate the static blank from the mold, and place the blank stably on the cutting table through turning to prepare for subsequent cutting.
10. Cutting Unit (Horizontal Cutting + Vertical Cutting)
Cut the demolded blank into blocks or plates that meet the specifications, with a cutting accuracy of up to ยฑ 1mm.
The horizontal cutting machine is responsible for cutting the blank in the horizontal direction, and the vertical cutting machine completes the cutting in the vertical direction.
11. Autoclave
It is the core equipment for AAC block production. It cures the cut blank with high-temperature and high – pressure steam (usually at a temperature of 180- 200โ and a pressure of 0.8- 1.2MPa) to promote the full reaction of raw materials and form a high – strength structure.
12. Pre-autoclave Conveyor
Neatly group the cut blanks and transport them to the entrance of the autoclave to ensure that the blanks enter the autoclave in an orderly manner.
13. Post-autoclave Conveyor
Transport the autoclaved and cured finished products from the autoclave to the subsequent processing area to complete the out – of – autoclave transfer.
14. Pallet Wrapper
Wrap and package the qualified finished blocks after inspection to fix the stacking form of the blocks for easy storage and transportation.
15. PLC Control System
As the control centre of the entire production line, it realizes functions such as monitoring of equipment operating parameters, automatic control of the production process and fault alarm.
