technical support.

Autoclaved lime-sand brick has replaced the traditional clay brick. Its raw materials are various so it is energy conservation and environmental protection. WIth the fly ash or slag or sand as its raw materials, it is added with lime, gypsum and aggregate, pressed into certain mode.

The major equipment in the complete equipment of brick making equipment are mixer, counteraction bin, brick making machine, roller machine, autoclave, etc., and auxiliary equipment are screw conveyor, electronic dosing machine, hardening car, and so on.

Production technology:

According to raw material's category, quality and technological characteristics of main equipments, different technologies can be adopted to produce sand aerated concrete block. Generally, fly ash or silica sand is grinded into slurry with water, and then mixed with lime powder, proper cement, gypsum and aluminum powder paste and finally filled into mould. After maintaining, foaming and solidifying, blocks or plank of different specifications will be cut out and conveyed by trolley into autoclave. Under the high temperature and saturated steaming curing, celluar and light-weight aerated concrete products will be formed. The steps are as follows:

(1) The raw materials such as lime, cement, gypsum, sand(or fly ash), etc are stored in silo(tank) for use after treatment.

(2) Aluminum powder or aluminum paste is stored for use after treatment.

(3) Raw material is measured by electrical scale with certain proportion. After measured, aluminum powder and water are fed into aluminum powder mixer to make into suspension liquid.

(4) Water for proportioning( cold water or hot water from hot water tank) is measured by electrical scale

(5) After measured, raw materials and aluminum liquid are fed into casting mixer orderly to be mixed evenly and cast in moulds(if making plank, then reinforcing mesh should be put in the mould before hand)

(6) After stopping and precuring under certain temperature for certain time, the green blocks will reach to certain strength. And then they are turned 90° by turning hanger and onto cutter for demoulding and cutting.
