talc is formed under hydrothermal conditions and is a typical mineral of weaker regional metamorphism (regional dynamo-thermometamorphism). It often occurs in association with chlorite, serpentine, or magnesite. The main parent rocks that undergo metamorphic mineral reactions leading to talc formation are either ( magnesite-bearing) siliceous dolomites, or olivine- and/or pyroxene- containing ultrabasics. Talc is a mineral composed of hydrated magnesium silicate with the chemical formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. Talc is used in many industries such as paper making, plastic, paint and coatings, rubber, food, electric cable, pharmaceuticals, cosmetics
The limestone is fed into the bucket elevator and subsequently transported to the raw material warehouse for grinding.
After grinding, the finished products are gathered by powder concentrator, and then conveyed to a screw conveyor.
The finished products are transported to the storage warehouse, while the excess gas is filtered by the dust collector.
The whole system is equipped with three pulse dust collectors to guarantee that the whole system is free of dust leakage.
The system is outfitted with an intelligent PLC control cabinet and an upper computer.
The system is equipped with an intelligent PLC control cabinet and an upper computer.
