Mica group represents 37 phyllosilicate minerals that have a layered or platy texture. Mica raw pulverized by CLIRIK mica vertical roller mill, mica pulveriser can be fine and super-fine mica powder the mica acts as a filler and extender, provides a smooth consistency, improves the workability of the compound, and provides resistance to cracking.
In the paint industry, ground mica or mica powder is used as a pigment extender that also facilitates suspension, reduces chalking, prevents shrinking and shearing of the paint film, increases resistance of the paint film to water penetration and weathering, and brightens the tone of colored pigments. Mica also promotes paint adhesion in aqueous and oleoresinous formulations. Also Dry-ground mica powder is used in the production of rolled roofing and asphalt shingles, where it serves as a surface coating to prevent sticking of adjacent surfaces.
 
The commercially important micas powders are muscovite and phlogopite, which are used in a variety of applications. Mica powder grinded by mica vertical roller mill can be used in more areas. So CLIRIK engineer will introduce CLIRIK mica vertical roller mill to you.
 
Detail introductions of mica vertical roller mill, mica dry grinding:
Mica vertical roller mill, mica dry grinding is mainly used in mining, building materials, chemical, metallurgical and other industries. It can process stone materials that moisture content less than 5%, Mohs hardness under 6 levels, such as kaolin, limestone, talc, barite, dolomite, calcite, marble, gypsum, bentonite, mica, graphite, and so on. The finished powder size can be 3000meshs.
HGM series mica vertical roller mill, mica dry grinding is the technology team of Shanghai Clirik machine Co., LTD through long-term research about mica characteristics, and field investigate production process of mica processing factory, overcome varies problems appeared in the process of mica making, developed new generation grinding equipment. The mica vertical roller mill, mica dry grinding is the result of our technical staff after years accumulated experience and test innovative, it can be used not only for mica powder processing, can also be used to manufacture calcite, barite, marble and other stone materials. It also has many appellations, such as calcite mill, barites mill, calcium carbonate mill, mica mill, dolomite mill. Mica vertical roller mill is the preferred stone grinding equipment.
A non-toxic mineral, mica can be helpful to humans, animals, plant life, and the environment. While the majority of mica produced in North America is used to manufacture mica panels or building plasters, mica can also be used: as a soil additive As an additive in turbid water, particularly ponds, to settle dirt and clay particles without injuring aquatic life, as a food additive, as a color additive for drugs and cosmetics, a primary ingredient in toothpaste. Mica also has played an important role in the entertainment industry.
 
Working principle of mica vertical roller mill:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse material return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
