HVM1300M Coal Vertical Mill/Coal Grinding Mill/Coal Powder Making Machine For Coal Powder

With the development of society and the progress of the industry, environmentally friendly, efficient, energy-saving and green grinding machine equipment is increasingly occupying a larger market share, becoming a powerful device to support the rapid development of society. Coal powder is a common fuel in the fuel industry. The more fully coal powder is burned, the more efficient it can be used. In the field of lime kiln calcination, coal powder is a commonly used fuel to promote development, and professional vertical grinding equipment promotes efficient production of coal powder processing.

Vertical mill, belonging to energy-saving and noise reducing grinding equipment, is also professionally manufactured in response to energy-saving and emission reduction production requirements. Vertical mill has the characteristics of drying, grinding, grading, and conveying, and is currently widely used in many fields such as coal mines, cement, slag, desulfurization in power plants, non-metallic mines, and so on.

HVM Vertical Mill 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.

【Performance characteristics of HVM Vertical Coal Mill】
Integrating drying, grinding, grading, and conveying, it features high grinding efficiency, low power consumption, large feed particle size, easy adjustment of product fineness, simple equipment process flow, small floor area, low noise, low dust, easy use and maintenance, low operating costs, and low consumption of wear-resistant materials.
