AAC Fixed Pouring Mixer

Application:

The pouring mixer is a mixing machine fixed on top of the block mould whose function is to mix material thoroughly before pouring so that they can made into AAC blocks.

Light Weight Block (AAC block)

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.

Main Equipments:

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.

Market Prospects of AAC Production

AAC block is a new type of wall material. It’s unique because it is a new material of lightweight thermal insulation. The Autoclaved Aerated Concrete Technology began 100 years ago, but the technology in China started relatively late, lagged more than four decades behind, however, our development in AAC industry is indeed very fast. Now the domestic technologies of this technology have been able to meet the international advanced level.

Saving land resources is the greatest advantage of AAC Production. It do not use lots of land, and its raw material sources are very broad, sand, slag, fly ash and coal etc. all can be used as its material. The performance characteristics of AAC are superior, not only with very good process capacity and thermal insulating capability, but also with very strong plasticity, it can be sawed easily.
