High pressure micro powder mill or high pressure mill is mainly consist of blower, super fineness analyze, powder accumulated machine, bag dust collector and connecting pipes and other components. Compared with other similar grinding mills, the grinding pressure of grinding roller to materials has increased 800 to 1200 kg under the impact of ultra-fine spring.

Performance characteristics of High Pressure Micro Powder Mill

1. Wider applicable range compared with jet mill

2. Energy saving. Under the situation of same yield and fineness, its energy consumption of system is only one-third of jet mill.

3. Low investment and high efficiency, under the situation of same yield and fineness, the price is only one-fourth of jet mill.

4. Less production processes. Compared with jet mill, the superfine mill can reach an average particle size of below 6.5 um at a time.

5. Large feeding granularity, the average particle sizes of one-time discharging granularity can be up to 6.5 um.

6. Sealing grinding device, which has good sealed performance.

7. Effect of duct removal can fully reach the national 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.
