HM Series Coarse Powder Mill

The HM series coarse powder mill is one kind of new high efficient grinding machine. This mill is mainly used for coarse powder and small size of sand producing. The output size can reach more than 90% of 0-3mm.
The HM coarse powder mill is widely used in metallurgy, mining, chemical, cement, construction, industrial and mining industries etc.

Coarse Powder Mill Working Principle:

Step with main shaft, bulk disk and roller bracket is driven by motor through reducer. Installed above bracket, roller assembly rotates with main shaft and swings freely meantime, this bring a large centrifugal force, which scatters bulk materials evenly in grinding intermediate layer between central roller and ring. The bulk materials in the coarse powder grinding mill are grinded into powder and fall on the bottom, and then discharged from discharging opening under the effect of synchronously-rotating scraper.

Feature Of Coarse Powder Mill:

1. High production capacity, high crushing ratio.
2. Low power consumption, uniform particle size.
3. Simple structure, easy to operate.
4. Low investment cost, easy management.
