High Efficiency HVM Vertical Coal Mill For Power Plant

What are the advantages of a vertical grinder?
1. Reliable performance
The new grinding roller sealing device has more reliable sealing performance, and the grinding roller limit device effectively ensures the severe movement caused by material breakage.
2. Single machine production capacity is large, energy consumption is more economical, and compared to ball mills, energy consumption is 40-50% lower.
3. Clean and environmentally friendly
The entire system has low vibration, low noise, overall sealing, and full negative pressure operation, which is a new energy-saving and consumption reducing technology.
4. Automated operations
PLC fully automatic control system, remote control, and easier operation.
5. Excellent quality of finished products
The finished product has good particle shape, narrow particle size distribution, good liquidity, high whiteness and purity, which can enhance the competitiveness of the powder market.
6. Low civil engineering costs
The complete system has fewer equipment, a compact structural layout, and a small footprint. Compared to ball mills, it saves 50% and can be arranged outdoors, resulting in low civil engineering costs.
7. Easy to maintain
The grinding roller can be turned out of the machine using a hydraulic device, and there is a lot of space for replacing the roller sleeve liner and repairing the mill. The grinding roller and grinding disc liner are made of special materials, and the service life of the entire machine is longer.

Working principle:
The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, materials move towards the edge of the grinding plate. When passing through the circular groove on the grinding plate, they are crushed by the grinding roller. The crushed materials are picked up by the Jet stream at the wind ring at the edge of the grinding plate. Large particles fall directly onto the grinding plate for grinding again. When the materials in the airflow pass through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding plate for grinding again. The qualified fine powder is grinded together with the airflow, Collect in the powder collection device, which is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.
