Explosion-proof Environmental Protection Coal Powder Vertical
Roller Mill Machines
Product Introduction
Vertical mill is an ideal large-scale grinding equipment, which is
widely used in cement, electric power, metallurgy, chemical
industry, non-metallic mining and other industries. It integrates
crushing, drying, grinding, grading and conveying, and has high
production efficiency. It can grind block, granular and powdery raw
materials into required powdery materials.
【Application Field】
Cement chemical, coal, electric power and other industries
【Outstanding Advantages】
- High grinding efficiency and low power consumption
- Simple and reliable operation, stable product quality
- The technological process is simple, and the functions of grinding,
drying and powder selection are completed at the same time.
- Small footprint, compact layout, and low investment in civil
construction

【Working Principle】
The motor drives the grinding disc to rotate through the reducer,
the material falls into the center of the grinding disc from the
feed inlet, and the hot air enters the mill from the air inlet.
Under the action of centrifugal force, the material moves to the
edge of the grinding disc, and is crushed by the grinding roller
when passing through the annular groove on the grinding disc. The
crushed material is carried by the high-speed airflow at the air
ring at the edge of the grinding disc, and the large particles fall
directly on the grinding disc. 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 on the
grinding disc for re-grinding, and the qualified fine powder is
milled together with the airflow and collected in the powder
collecting device, which is product. Moisture-containing materials
are dried during contact with hot gas to achieve the required
product moisture.
With its scientific and reasonable design and unique structural
advantages, HVM vertical mill is widely used in the grinding of
various types of materials in all walks of life. Easy-to-grind
materials, the product fineness ranges from coarse to fine, the
types of powders handled are rich, and there are many industries
involved:
Moisture of grinding materials:
from materials with water content of 20-30% (such as carbide slag,
lignite, chalk, etc.) to materials with water content of less than
1% (cement clinker, etc.), the material has strong adaptability;
Industries where HVM vertical mills are used: building materials,
electric power, steel, energy, thermal power, chemical industry,
coal chemical industry, non-ferrous metallurgy, lime kiln, mineral
processing and other industries.
Materials that can be processed by HVM vertical mill:
ferrite, slag, slag, cement, diamond, iron ore, chrome ore,
manganese ore, gold ore, copper ore, aluminum ore, lead-zinc ore,
tantalum-niobium ore, polymetallic ore, nickel ore, bauxite,
silicon carbide, titanium dioxide, talc, bentonite, calcite,
kaolin, graphite, mica, wollastonite, feldspar, dolomite,
pyrophyllite, quartz sand, fluorite, limestone, organic Silicon,
hectorite, shale, volcanic ash, coal, etc.
