Mica is a rock forming mineral, typically in the form of pseudo hexagonal or rhombic plate-like, flaky, or columnar crystal shapes. The characteristics of mica are insulation, high temperature resistance, luster, stable physical and chemical properties, good thermal insulation, elasticity, and toughness. The most commonly used material in industry is muscovite, followed by muscovite. It is widely used in the building materials industry, fire protection industry, fire extinguishing agents, welding electrodes, plastics, electrical insulation, papermaking, asphalt paper, rubber, pearl pigments and other chemical industries.

Mica Powder Production Equipment - Mica Grinding Machine Equipment Composition: Hammer crusher, bucket elevator, storage bin, vibrating feeder, micro powder grinding host, frequency conversion classifier, dual cyclone powder collector, pulse dust removal system, high-pressure fan, air compressor, electrical control system.

Working principle:

During operation, the main motor drives the spindle and turntable to rotate through a reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway. Large pieces of material are crushed into small particles by a hammer crusher and then sent to the storage bin by a hoist. After passing through a vibrating feeder and an inclined feeding pipe, the material is evenly delivered to the upper part of the turntable's bulk tray.

The material disperses around the circumference under the action of centrifugal force and falls into the raceway of the grinding ring, where it is impacted, rolled, and ground by the ring rollers. After being processed into powder through three layers of raceway, the high-pressure fan sucks in external air into the machine through suction and brings the crushed material into the powder selection machine. The rotating impeller inside the powder selector causes the coarse material to fall back and be re ground. The fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged by the discharge valve at the bottom, which is the finished product. The airflow with a small amount of fine dust is purified by the pulse dust collector and discharged through the fan and muffler.

Mica powder production equipment - Performance characteristics of mica milling machine:

1. Efficient and energy-saving

When the fineness of the finished product and the power of the motor are the same, the output is more than twice as high as that of the air flow mill, stirring mill, and ball mill.

2. Long service life of vulnerable parts

The grinding roller and grinding ring are forged from special materials, greatly improving their utilization. Under the same fineness of materials and finished products, the service life of worn parts is 2-5 times longer than that of impact crushers and turbine crushers, generally reaching more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years.

3. High safety and reliability

Due to the absence of rolling bearings and screws in the grinding chamber, there is no problem of bearings and their seals being easily damaged, and there is no problem of screws becoming loose and damaging the machine.

4. High fineness of the product

The product fineness can reach D97 ≤ 5 μ m in one go.

5. Environmental protection and cleanliness

Using a pulse dust collector to capture dust and a muffler to reduce noise, it has the characteristics of environmental protection and cleanliness.

Technical parameters:

Industrial use of mica powder:

The specifications of mica powder include 1-6 mesh, 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-60 mesh, 60-80 mesh, 80-100 mesh, 150 mesh, 200 mesh, 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh, etc. The specifications can be produced according to requirements.

The most commonly used material in industry is muscovite, followed by muscovite. It is widely used in the building materials industry, fire protection industry, fire extinguishing agents, welding electrodes, plastics, electrical insulation, papermaking, asphalt paper, rubber, pearl pigments and other chemical industries. Ultra fine mica powder can be used as functional filler for plastics, coatings, paints, rubber, etc., to improve its mechanical strength, enhance its toughness, adhesion, anti-aging and corrosion resistance. In addition to its extremely high electrical insulation, resistance to acid and alkali corrosion, elasticity, toughness and sliding properties, heat resistance and sound insulation, and low coefficient of thermal expansion, it also pioneered the characteristics of smooth surface, large diameter to thickness ratio, regular shape, and strong adhesion of the sheet body.

In industry, it is mainly used as an insulation material for electrical equipment and electrical devices due to its insulation and heat resistance, as well as its resistance to acid, alkali, pressure, and delamination; Secondly, it is used to manufacture furnace windows and mechanical parts for steam boilers and smelting furnaces. Mica flakes and mica powder can be processed into mica paper, and can also replace mica flakes to manufacture various low-cost and uniformly thick insulation materials.
