Product Description of Mica Powder Ultrafine Grinding Mill

The mica powder ultrafine grinding mill production line is mainly suitable for grinding various non-flammable and flammable materials with a Mohs hardness below 9 and a humidity below 6% in industries such as building materials, chemicals, fertilizers, metallurgy, mining, refractory materials, ceramics, steel, thermal power, and coal. The fineness of the finished product can be adjusted from 325 mesh to 3000 mesh.

Mica is a rock-forming mineral, usually in the form of pseudo-hexagonal or rhombic plate, flake, and columnar crystals. The color varies with the chemical composition and becomes darker mainly with the increase of Fe content.

The characteristics of mica are insulation, high temperature resistance, luster, stable physical and chemical properties, good heat insulation, elasticity and toughness.

The most commonly used in industry is muscovite, followed by phlogopite. It is widely used in building materials industry, fire protection industry, fire extinguishing agent, welding rod, plastic, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigments and other chemical industries.

Working Principle of Mica Powder Ultrafine Grinding Mill

The grinding chamber of the mica powder ultrafine grinding mill contains a set of rotating and stationary grinding discs. These discs create a high-speed collision between the mica particles, leading to their comminution.

The rotation of the grinding discs generates centrifugal force, which throws the mica particles towards the outer periphery of the grinding chamber.

As the mica particles move towards the periphery, they collide with each other due to the centrifugal force. These collisions lead to the breakage of the particles into smaller sizes. Additionally, there is friction between the particles, further contributing to the grinding process.

The ground mica particles are carried upward by the airflow into the classifier system. The classifier separates the finer particles from the coarser ones, ensuring that only the desired ultrafine particles are collected.

The airflow, induced by a fan, helps in transporting the mica particles through the mill and into the classifier. The finer particles that meet the required size criteria are collected as the final product, while coarser particles are returned to the grinding chamber for further comminution.

The ultrafine mica powder is collected in a separate container or bag for further processing or packaging.

Mica processing and production process

Mica ore flotation is used to recover mica and fine-grained mica below 14 mesh in pegmatite and mica schist. In my country, the flotation of mica ore has not been applied in production. The winnowing method is suitable for areas lacking water sources and has been used in actual production.

The first stage
Ore beneficiation, flotation and winnowing of mica.

The second stage
① Mica and gangue are sorted by the difference in surface physical and chemical properties.
② Crushing → screening and classification → wind selection.

The third stage
① The ore is crushed and ground to dissociate the mica monomer. Under the action of the agent, the mica becomes a foam product and separates from the gangue.
② After the ore is crushed, the mica basically forms a flake. The gangue minerals feldspar and quartz are massive particles.

The fourth stage
Break up the packaging for the finished product.
