High Efficiency Bauxite Vertical Roller Mill

Bauxite vertical mill is a specialized grinding equipment designed for processing bauxite with Mohs hardness 3-4, widely used in refractory, alumina, and cement industries. It achieves output fineness of 10-40μm with capacity ranging from 1 to 45 t/h.

Technical Parameter

How It Works:

The motor drives the grinding disc to rotate via a reducer. Raw materials fall onto the center of the grinding disc through the feed inlet, while hot air enters the mill from the air intake.

Under centrifugal force, materials move toward the edge of the grinding disc. As they pass through the annular grooves on the disc, they are crushed and pulverized by the grinding rollers.

The pulverized materials are lifted up by high-speed airflow at the air ring around the edge of the grinding disc. Coarse particles fall back onto the disc for re-grinding.

Materials carried by the airflow pass through the dynamic classifier. Driven by rotating rotors, coarse powder falls back to the grinding disc for secondary pulverization, while qualified fine powder is carried out of the mill by the airflow and collected by the powder collecting device as finished products.

Moist materials are dried during contact with hot gas to reach the required moisture content of the finished products.

Bauxite Vertical Mill for Different Applications
Refractory Industry

Bauxite vertical mill produces refractory-grade bauxite powder with controlled particle size distribution for high-alumina refractory bricks and castables. Recommended fineness: 200-325 mesh.

Alumina Production

In Bayer process alumina plants, bauxite vertical mill prepares raw material for digestion, ensuring consistent particle size and maximizing alumina extraction rate.

Cement & Ceramic

Suitable for grinding bauxite as cement additive and ceramic raw material, with adjustable fineness to meet different formulation requirements.
