Coal powder is a commonly used fuel in national production and daily life, and grinding coal powder naturally requires strong support from professional grinding equipment. Coal powder belongs to flammable and explosive substances, so the selected grinding machine equipment needs to be professional, efficient, noise reducing, and environmentally friendly. Guilin Mining Machinery can provide professional coal powder vertical grinding equipment to meet the material characteristics and industry needs of coal mines, and assist the coal grinding production needs of lime plants.

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.

HVM Vertical Mill
【Grinding Field】: For various non-metallic mineral materials with Mohs scale hardness below 7 and humidity within 6%, the grinder is widely used in the production fields of power, metallurgy, cement, chemical industry, rubber, paint, ink, food, medicine, etc.
【Performance Characteristics】: It integrates drying, grinding, grading, and conveying, with 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.

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.
