Product Description
 Ultra fine grinding mill is capable of grinding various materials with hardness levels ranging from low to medium. It can handle materials with a Mohs hardness of up to 9 and a moisture content of up to 6%. Some common materials processed by micro powder grinding mills include limestone, calcite, marble, talc, barite, dolomite, and kaolin, etc.

Work Principle:
Ultra fine grinding mill utilizes a combination of attrition and impact forces to reduce the size of the particles. It operates by rotating a set of grinding rollers or discs at a high speed, which creates a strong centrifugal force. The material is fed into the grinding chamber and is subjected to grinding, crushing, and impact between the rollers or discs and the grinding ring.

 • The yield is 40% higher than other mills.
• High utilization rate of Wear material:2-5years.

• Adjustable particle size:325-3000mesh.
• High safety and reliability. The design of the mill is rigorous, so no screw loosening to damage the machine.
• Closed system, so it is the green and ideal equipment for environment protection.
