Products description:

Vertical coal mill can be widely used in cement, electricity, steel, metallurgy and other industries. As for coal mill special process and structure, there is less dust during the production process, low noise, high efficiency coal out put and excellent combustion performance. CHAENG coal mill vertical process is simple and compact, pulverized coal fineness can up to 80 μmR 3%, and the fineness is stability and homogeneous.

Vertical coal mill structure principle:

The operation of vertical coal mill is driven by the motor, through the planetary reducer mill to make mill rotation, the 2-4 roller in the disc driven by the rotation, the coal from coal pipe is distribution on the millstone, due to hydraulic loading force, grinding roller and the millstone will make the extrusion of large particles raw coal crushed. The sliding friction force make small coal particles crushed, when the raw coal is milled in the millstone, which will be dried by hot air, if the coal powder achieved the finished coal requirement will through the wind conveyor into the separator for separation. The qualified coal was transported to the coal storage, the failure of coarse coal powder return to mill for re-grinding.

Technical advantages:

High efficiency, large capacity

THE vertical coal mill has high efficient performance, compared with the same model of old vertical mill, which can increase 20-50% in output, and can greatly reduce the coal mill operation power consumption.

High quality of coal pulverize

The vertical coal mill uses the most advanced combination of dynamic and static separator, which separator classification efficiency is high , large room for adjustment, fineness choosing can up to 0.08 mm, sieve residue of less than 8%, the vertical coal mill can meet the fineness requirement of poor coal or anthracite grinding in cement production line.

Highly system security

Adopts temperature detection devices, on-line gas analyzer and other anti-explosion measures, which can effectively ensure the of equipment safe operation .

Achieve environmental standards

Through the unique sealing structure design, the whole system is in the negative pressure state, during the production process, there is no dust spillover in the production process, the noise is small, the pulverized coal collection uses the special-purpose gas box pulse dust precipitator, the dust emission density is suit for the national standard.
