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.
