Working Principle
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when it passes through the annular groove on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is milled together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.

【Product Advantages】
1. Large output and high work efficiency.
2. The grinding roller bearing adopts the thin oil circulating lubrication method, which can ensure that the bearing works at a lower temperature, and at the same time, the quality and purity of the lubricating oil can be controlled, which is beneficial to prolong the service life of the bearing;
3. Equipped with roller turning device, which can turn the grinding roller out of the mill for easy maintenance;
4. Compared with some other forms of roller mills, the hydraulic system of the vertical mill has low operating pressure, low oil leakage failure rate, and high safety and reliability;
5. The new high-efficiency cage rotor powder separator has high powder efficiency.
