AAC Block Production Line Process Unit

  Fist of all, close and match stored raw materials (1) and feed them into pouring mixer, after evenly mixing (2) they are poured (3) in the mould to be reinforced by steel bars for slabs(19). After pre-curing (4) under a certain temperature for a period of time, the blank shall have a certain of hardness. The mould and the blank shall be then hanged to the cutting machinery by the tilting hanger to fulfil following actions: a. tilting the mould 90°in the air (5)(One side plate of the mould become the bottom to support the blank until end product is hardened); b. Hanged to the cart or the cutting support to open mould or demoulding(6); c. The demoulded frame and returned side plate shall be reorganized into the mould(16), and shall be ready for next pouring after cleaning and oil spraying(17)(18). The blank then be cut on the cutting machinery in six sides: a. first, two Vertical sides of the blank are cut(7); b. Then the horizontal cutting longitudinally(8); c. And the horizontal cutting cross cutting or chopper-like cutting at last(9). The cut blank and the bottom are hanged by the semi-product hanger to the hardening car(10), hardened under high temperature(11)(12). After that, end product leaves the autoclave(13) and is hanged by the end product hanger to be stacked or loaded(14) and packed(15). The hardening plates are returned(16).

Advantage Of AAC Block

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Anti-seismic: The same building structure, improve the two seismic than the brick level.
7. Green: Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
8. 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.
9. 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.
10. Economies: 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.

Main Equipments of AAC Block Production Line

• Material-Milling Equipments

• Crusher:Lime,gypsum,and such kind of bulk material need to be crushed as the fisrt step in AAC Block Production Line
• Ball Mill:The raw material of AAC Blcok must be fully grinded in order to make better reaction .Ball Mill is widely used in powder-making production line including cement,building material ,chemical raw material,fertilizer,ore dressing of ferrous metal and non-ferrous metal,etc.
