Professional Energy Efficient Vertical Roller Grinding Mill Prices
For Vertical Coal Mill Plant
Product Introduction
HVM vertical roller mill is an energy-saving grinding equipment
that combines mature vertical grinding technology, successful
foreign experience, and our company's technological innovation and
upgrading. It integrates crushing, drying, grinding, grading, and
conveying, and can be widely used in industries such as cement,
electricity, metallurgy, chemical, and non-metallic minerals. It
focuses on three major fields: non-metallic minerals, coal powder,
and slag.
Scope of application: sand and gravel yard, concrete mixing plant, dry mortar, power
plant desulfurization, quartz sand, etc.
Materials: river pebble, granite, basalt, quartz, iron ore,
diabase, limestone, calcite, dolomite, barite, talc, gypsum,
bentonite, etc
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, the material moves towards the edge of the
grinding disc and is crushed by the grinding roller when passing
through the circular groove on the grinding disc. The crushed
material is carried up by the high-speed airflow at the edge of the
grinding disc, and large particles directly fall onto the grinding
disc for re grinding. When the material in the airflow passes
through the dynamic and static separator, under the action of the
rotating rotor, the coarse powder falls onto the grinding disc for
re grinding, and qualified fine powder is discharged with the
airflow, Collect in the powder collection device, which is the
product. Materials containing water are dried in the Contact
process with hot gas to meet the required product moisture.

Advantage
Low operating cost:
The grinding roller directly crushes and crushes the material on
the grinding disc, which has low energy consumption and saves 40%
to 50% energy compared to the ball milling system.
Less wear: The grinding roller does not come into direct contact
with the grinding disc during work, and the grinding roller and
lining plate are made of high-quality materials, resulting in long
service life and less wear.
Stable product quality
(1) Due to the short residence time of materials in the mill, it is
easy to detect and control product particle size and chemical
composition, reduce repeated grinding, and stabilize product
quality.
(2) The iron content in the product is very low, and the mechanical
wear iron contained is easy to remove. When used for grinding white
or transparent materials, the whiteness and cleanliness of the
product are high.
Low investment costs
Due to the integration of crushing, drying, grinding, and grading
transportation, the system is simple and compact, covering an area
of about 50% of the ball milling system, and can be arranged
outdoors, which can greatly reduce investment costs.
Dry
The hot air that enters the mill from the outside directly and
repeatedly comes into full contact with powdered materials inside
the mill, with strong drying ability. It can save one dryer and
energy for the mill system. By adjusting the temperature of the hot
air, it can meet the requirements of materials with different
humidity.
Easy to operate and maintain
(1) Equipped with an automatic control system, it can achieve
remote control and is easy to operate.
(2) Equipped with a limit device to prevent direct contact between
the roller sleeve and the grinding disc liner, it avoids
destructive impact and severe vibration.
(3) By repairing the oil cylinder, flipping the boom, replacing the
roller sleeve and lining plate, it is convenient and quick to
reduce downtime losses.
Environmental cleaning
Low vibration, low noise, and overall sealing of the equipment. The
system operates under negative pressure, without dust leakage, and
the environment is clean, meeting environmental requirements.
