Product Details

What kind of coal mill is better for coal powder production?

Vertical coal mills are generally used for grinding coal powder. The complete vertical coal mill system is widely used in the preparation of coal powder, and the technology is relatively mature. The vertical coal mill adopts the principle of rolling and crushing with grinding rollers and plates, which can fully grind the coal powder to the required fineness. At the same time, the entire equipment is equipped with a CO-O2 online analysis system, a grinding roller hydraulic device, and an automated electronic control device. The entire equipment makes the entire milling process safe, intelligent, convenient, and energy-efficient and environmentally friendly.

 

Scope of application: Suitable for users with high requirements for coal powder production.
Preparation of coal powder processing range: 5-100T/H.
 
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.
