Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in a variety of products ranging from drywalls, paints, fillers, especially in parts for automobiles, roofing and shingles, electronics etc. The mineral is also used in cosmetics to add "shimmer" or "frost."
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.

Black mica has good insulation, heat resistance, acid and alkali resistance, so it is usually used for making the insulating materials of electrical facilities. Besides, it can be used to produce the furnace window and mechanical parts of steam boilers and smelting furnace.
When mica is used for making coating materials, its unique structure can block UV light, and its stability can effectively enhance the permeability resistance, weather resistance, wear resistance and corrosion resistance of coating materials. Because there are no radioactive elements, mica can be widely used as coatings in various industries.
Plastic mica powder is a kind of natural functional powder filling material because of its high temperature resistance, acid and alkali resistance, wear resistance, etc. The high temperature resistance of mica powder is helpful for producing spare parts used under hot environment. Compared with glass fiber, plastic made of mica powder usually boasts smooth surface, no warpage and deformation. The product is widely used in PP, PA, PBT and PET fields.
