High pressure micro powder mill is composed of main machine, air blower, super-fine analytical engine, cyclone powder collector for final products, bag type dust collector and connecting pipe and other auxiliary equipment such as bucket elevator, material storage bin, electronic control box, powder feeder and crusher can be equipped according to the requirements of the customers. Inside the grinding room of the micro powder mill, the grinding roll assembly hangs on the cradle of the grinding roll through the corss arm. The cradle of the grinding roll, principal axis and the relieving tool post are fixed and connected and the pressure spring tightly presses on the outside end of the cantilever of the bearing room of the grinding roller through the tension bar. The corss arm bearing is the supporting point, and the grinding roll is tightly pressed to the surface of the inner circle of the grinding ring through the spring pressure. When electro motor rotates through the transmission device, the relieving tool on the relieving tool post and the grinding roll will synchronously rotate, and the grinding roll also rotates around itself while rolling on the surface of the inner circle of the grinding ring, and the analytical engine drives the impeller to rotate through the transmission device, and the adjustment of the speed of the analytical engine will determine the fineness of the final powders. 

Performance Features

1. High pressure micro powder mill has wide application ranges compared with airflow mill.

2. Compared with other grinding mills, the grinding force of the grinding roll of high pressure micro powder mill is improved by 800-1200Kg under the high pressure spring.

3. High pressure micro powder mill saves more energy. When the output and the fineness are the same, the energy consumption of this system is only one third that of the airflow mill.

4. High pressure micro powder mill has small investment and high profits. . When the output and the fineness are the same, the price of the high pressure micro powder mill is only one eight that of the airflow mill.

5. The feeding granularity of high pressure micro powder mill is big.

6. Eclipsed form and multi-level sealed grinding device has fine sealing performance.

7. The dust collection effect of high pressure micro powder mill completely reaches the national powder dust emission standard. 

Working Principle

Inside the grinding room of the micro powder mill, the grinding roll assembly hangs on the cradle of the grinding roll through the corss arm. The cradle of the grinding roll, principal axis and the relieving tool post are fixed and connected and the pressure spring tightly presses on the outside end of the cantilever of the bearing room of the grinding roller through the tension bar. The cross arm bearing is the supporting point, and the grinding roll is tightly pressed to the surface of the inner circle of the grinding ring through the spring pressure. When electro motor rotates through the transmission device, the relieving tool on the relieving tool post and the grinding roll will synchronously rotate, and the grinding roll also rotates around itself while rolling on the surface of the inner circle of the grinding ring, and the analytical engine drives the impeller to rotate through the transmission device, and the adjustment of the speed of the analytical engine will determine the fineness of the final powders.
