Mica grinder mill, Mica application
Mica is a kind of rock-forming minerals. Mica is characterized by insulation, high temperature, shiny, stable physical and chemical properties, good thermal insulation, elasticity and toughness. Most used in industry is muscovite, followed by phlogopite. Its widely used in building materials industry, the fire industry, fire extinguishing agents, welding, plastics, electrical insulation, paper, asphalt paper, rubber, pearlescent pigments and other chemical industries
Mica mineral:
India is the leading producer of muscovite mica followed by Brazil. Other producing countries are the USA, Tanzania, Rhodesia and Argentina. The USA generally produces scrap mica. The leading producers of phlogopite mica are Malagasy Republic and Tanzania whose average annual production are 1,000 tonnes and 300 tonnes respectively. Small production of phologopite is reported from Canada, Tanzania and India.
Mica powder:
Mica powder in various forms is obtained by grinder, breaking mica scrap, which is a slow, costly and extremely complicated process, because of the scrap being tough and having a plate like structure.
The mica obtained from the mine is called crude mica. It requires a little dressing to remove associated pegmatite dirt as well as defective portions such as buckled, wrinkled and wavy mica. They are rifted away with sickel.
Book-mica, split into a size atleast covering an area of 2 1/2 inch and about 1/8 inch thick is called block mica. Block mica split into thin films of thickness 0.004-0.0012 inch is claled mica-film and less than 0.0012 inch thick as splitting.
The laboureres engaged in mica mines and factories where mica is hand-dressed are experts in dressing the crude mica into block, films and splittings. They do it by visual aid only. During the course of processing a considerable portion of mica goea waste. It is termed as scrap mica. The ratio of scrap mica to crude may vary from 60 to 80% depending on the defective portion in the crude mica.
