CRGM series superfine grinding mill for mineral Ultra Fine Grinding Mill is a device that breaks solid materials into powder by grinding, Such comminution is an important unit operation in many processes. It is usually used in Metallurgy, building materials, chemical and mine industries. 

Working Principle of Ultra Fine Grinding Mill

When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.

The high-pressure air blower constantly inhales air within the grinding mill and, in turn,  the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, move to the dust cleaner, and cling to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The conveyor sends the materials from the above two lots at the bottom to get the finished powders packed. In addition, filtered clean air will be emitted from the air outlet of the muffler in the end.

Benefits of Ultra Fine Grinding Mill

• 1. The yield is 40% higher than other mills.

• 2. High utilization rate of Wear material:2-5years.

• 3. Adjustable particle size:325-3000mesh.

• 4. High safety and reliability. The design of the mill is rigorous, so no screw loosening to damage the machine.

• 5. Closed system, so it is the green and ideal equipment for environmental protection.
