Fine coal is the main energy source for people's daily production
and life, and the grinding of fine coal naturally relies on
professional grinding equipment. Due to the fact that coal powder
is a flammable and explosive substance, the selected crusher must
be professional, efficient, noise reducing, and environmentally
friendly.
In the development of society and the progress of industries,
environmentally friendly, efficient, energy-saving and
environmentally friendly grinding machine equipment has an
increasing market share, and it has become a powerful device that
can help society develop rapidly. In the coal industry, pulverized
coal is the most common one. The more fully it burns, the higher
its utilization rate will be. Pulverized coal is a common fuel in
the calcination process of lime kiln, and professional vertical
mill equipment is helpful to improve the processing efficiency and
output of pulverized coal.
Vertical grinding machine is an efficient, energy-saving, and noise
reducing grinding equipment, as well as a new type of grinding
equipment specially developed in response to the production needs
of energy conservation and emission reduction. Vertical mill is a
new type of mill that integrates drying, fine grinding,
classification, and transportation. It has been widely used in
various industries such as coal, cement, slag, desulfurization in
power plants, and non-metallic minerals.
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.
