Mica powder grinding mill， Mica powder processing plant
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 grinding, 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.
For commercial purposes, mica is graded according to the quality e.g. superfine, clear, stained, fairly stained, good stained, heavily stained and densely stained.
How to produce the Mica powder?
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 materials 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.
