Large Capacity Environmentally Friendly Coal Powder Vertical Roller Mill

Description:

Vertical coal mill, also known as vertical coal mill, vertical coal mill, coal pulverizer and coal mill, is a common equipment for pulverizing coal in limestone kiln calcination, boiler heating industry, glass plant furnace transformation, cement plant, thermal power plant, steel plant and other fields.

Pulverized coal mines include raw coal, bituminous coal, coking coal, fat coal, gas coal, long flame coal, lean coal, etc. Hefei Hengcheng's vertical coal mill has advanced production technology, is equipped with anti-static treatment and explosion-proof devices, and uses an open circuit system. It is an excellent equipment for pulverized coal grinding.

【Working principle】

The motor drives the grinding plate to rotate through the reducer, the material falls in the center of the grinding plate from the feed inlet, and the hot air enters the mill 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 carried away at the edge of the grinding plate by the high-speed airflow at the wind ring. Large particles directly fall onto the grinding plate for re grinding. When the materials in the airflow pass through the dynamic and static separators, under the action of the rotating rotor, the coarse powder falls onto the grinding plate for re grinding. The qualified fine powder is grinded together with the airflow, The product is collected in the powder collecting device.

Materials containing water are dried in the process of contacting with hot gas to reach the required product moisture.

Re:

1.HGI≥50

2.Coal Fineness ≤3% when grinding anthracite,the capacity will go down

【Advantages and characteristics of vertical coal mill】

High yield
The production capacity of the single machine is large, the feeding strength is large, and the powder output rate is high.

Mass Production
It integrates drying, grinding, grading and conveying, and is highly efficient and energy-saving. It solves the problems of low capacity and high energy consumption of ordinary mills.

Low Maintenance Rate
Low wear, the grinding roller and grinding disc lining plate are made of special materials, with long service life and low maintenance rate.

High Degree of Automation
The PLC automatic control system is used for the whole process remote control, which is easy to operate.

Mature Ventilation Technology
With strong drying capacity, hot air can be directly used to dry the moisture of raw materials, which can transform from drying to grinding.

High dust collection efficiency, meeting environmental requirements
The whole system is sealed and operates under full negative pressure, basically without dust overflow, with high dust collection efficiency, meeting the production requirements of energy conservation and emission reduction.
