Main Equipments in AAC Production Line

Material-milling Equipments: 1 Crusher: Lime, gypsum, and such kind of bulk material need to be crushed as the first step in AAC Plant. 2 Miller: The AAC material must be fully grinded in order to make better reaction. Ball Mill is used widely, it has two types: dry and wet, can be chosen upon requirement.

Material Metering Equipments: Computer Control Automatic Metering System is commonly used as measurement of raw materials.

Material mixing and casting equipments: Mixer, it’s the slurry mixing machine, also is slurry casting machine.

Cutting Machine: the AAC blank is formed after casting and pre-curing, as the size is too large, it must be cut to achieve the required product size.

Autoclave: Autoclave is a device for silicate hydration products to get physical and mechanical properties.

Boiler: the boiler supports for the autoclave and pre-heat furnace and other facilities with heat.

Auxiliary Equipments: 1 Mould Frame, Mould Bottom and Mould Car, they composed together to form the Casting Mould, which is the main forming equipments in AAC Production Line. 2 Hardening Cart, Ferry Cart and Hangers, they must be equipped as auxiliary equipments in autoclave curing system.

The Performance Advantage

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.
