AAC plant included the cutting machine, ball mill, autoclave, crusher upside hoist, Mixing system, control system, etc. The autoclave aerated concrete plant simple name is AAC equipment, Production Process of Aerated Concrete According to the category and quality of raw material, and the features of equipment, the aerated concrete can be manufactured in different processes. Zhengzhou Kehai Heavy Industrial Machinery Co., Ltd is most professional manufacturer of autoclaved aerated concrete (AAC) plants for more than 30 years, and we can supply complete set of autoclaved aerated concrete plant with 50000, 100000, 150000, 200000, 250000, 300000, 350000m3 capacity annually (from 200 m3 to 1000 m3 per day), including plant design, equipments installation, technical instruction, personal training, etc., and also can design and manufacture as per clients' requirement.

Production Engineering of AAC plant:
1. Firstly, dose and match measured raw materials(crushing raw material)
2. After distributing, feed raw material into pouring mixer to make slurry
3. Through thoroughly mixing, the slurry is poured to mould
4. After pre-curing with a certain temperature & time, the block would reach certain hardness prepare for cutting
5. Upside hoister would turn over 90 degree of mould, and delivery the mould with blank(big block before cutting) to cutting machine.
6. Then open the mould & separate it from blank, put the blank with side plate on cutting cart
7. The catting cart take the blank to cutting machine; firstly, vertical cut, then cross cut.
8. After cutting, the block is hanged to hardening car(hardeniong cart) with side plate by semi-finished product hoister
9. Group the cutted blocks and put them into autoclave
10. Hardening the blocks under certain temperature and pressure
11. Take finished products out of autoclave
12. The finished product hoister takes the finished product to stock shield
13. Packed for loading
14. The side plate return back by side plate roller
15. Side plate would be organized with open mould for recycling.
17. Clean the mould and preparing for next pouring
The Performance Advantage of AAC block
Lightweight: Porosity achieve 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building.
Fireproof: Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach to 245 minutes fire resistance, 300mm thick up wall can reach to 520 minutes fire resistance.
Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.
Anti-seismic: The same building structure, improve the two seismic than the brick level.
Pro-environment: Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
Durability: material strength is stability, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable after ten years.
Shortcut: it has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.
Cost-saving: An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
