What Kind Of Mica Grinding Mill Can Be Used To Produce Ultrafine Mica Powder?

As we all know, mica is a kind of hard-to-grind mineral, and its Bond Gong index is 148. The traditional medium stirring and grinding process of ultra-micronized mica not only takes a long time to grind, but also needs to add water. The wet grinding process is more complicated. Many dry ultra-micronized mica need to add grinding aid, and then separate the grinding aid after the ultra-micronized mica, which increases the process. How to make the mica ultra-micronization process simple and meet the requirements of different applications, and solve the tedious problems caused by the addition of grinding aids and the use of wet processing technology? HCMilling(Guilin Hongcheng), as a manufacturer of mica ultra-fine grinding mill, will introduce the mica superfine mill for ultra-fine mica powder production as follows:

Mica belongs to the aluminosilicate minerals and is divided into three subgroups: muscovite, biotite and lepidolite. Muscovite has high dielectric strength and resistance, low dielectric loss and arc resistance and other excellent dielectric properties, high temperature resistance, acid and alkali resistance, stable chemical properties, high mechanical strength, transparency and good splitting properties. It has good elasticity and flexibility, and is widely used in industry. With the continuous development of industrial technology, the requirements for the particle size of mica products are getting higher and higher. When the particle size of ultra-fine mica powder is less than 100 mesh, ultra-fine mica powder can be used in paint, rubber, glass fiber reinforced plastic, ceramics, plastics, cement, coatings It can also be used to produce mica paper and as a seed crystal for the production of synthetic mica, which solves the problems of poor heat resistance, low insulation, unstable chemical properties and low mechanical strength of traditional materials. Currently, the main challenges facing the production of ultrafine mica powder are:

1) The demand for ultrafine powders smaller than 1 μm increases rapidly;

2) The large-scale production of ultra-fine powder requires large-scale and intelligent equipment to reduce energy consumption per unit of product and stabilize product quality;

3) Large-scale supporting production of ultra-fine powder and strict product particle size distribution require fine classification equipment with large processing capacity, high classification efficiency and low energy consumption;

4) The processing of high-hardness ultra-fine powder materials and the continuous improvement of product purity requirements require that the wear of ultra-fine grinding and fine classification equipment be significantly reduced.

What mill is used for the production of ultrafine mica powder? HCM double-disc micro-powder impact mill is developed by HCMilling(Guilin Hongcheng) mica ultra-fine grinding mill manufacturer based on the above development direction. The main machine is mainly composed of grinding chamber, turntable, feeding mechanism and other structures. The material to be pulverized is crushed into particles < 10 mm by a crusher. It is sent to the storage hopper by the elevator, and the speed-adjustable screw feeder is transported from the hopper to the turntables in the host cavity on both sides. Utilizing the violent impact of the hammer, blade, rod, etc. on the high-speed rotating body with the material, at the same time, the gap between the impact hammer and the lining plate is impacted, worn, and sheared to achieve ultra-fine crushing of the material. By optimizing the working parameters of the classifier and induced draft fan, the control of the mica output and the discharge particle size can be realized, which can meet the requirements of different application fields and solve the secondary treatment problems existing in traditional grinding aids and wet processing.
