Clay, sticky soil containing little sand, is very small particles of aluminum silicate. In addition to aluminum, clay also contains small amounts of magnesium, iron, sodium, potassium and calcium, it is an important mineral raw materials.
First stage: Since clay’s water content is relatively high, raw materials need to be dried to moisture less than 6%. After drying, clay is transported by special vehicles to raw materials bin.
Second stage: Dry clay is lifted to the hopper by hoist, then transported by feeder.
Third stage: Qualified products after the grinding process enter the collector through classifier and pipe. The discharged powder is finished product. Unqualified powder cannot pass the classifier, and falls back to the main unit.
Fourth stage: The purified air stream flows into the blower through pipe above the collector. The air duct is circular, it is negative pressure pipe flow, except for the grinding chamber and blower, so indoor air conditions are good.
