Low Energy Consumption Less Noise Coal Powder Vertical Roller Mill Grinding Mill Machines
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.

Structural Principle
The vertical coal mill is driven by the motor reducer to drive the grinding plate to rotate. The raw coal materials are sent to the center of the grinding plate. Under the action of centrifugal force, the coal mine enters the grinding roller table. Under the pressure of the grinding roller, the coal mine is squeezed, ground, sheared, and then crushed. At the same time of grinding, hot air can be directly passed through. The drying capacity is strong. When drying the raw coal moisture, the hot air will be uniformly sprayed upward. The pulverized coal after grinding is blown by the high-speed air flow, Coarse pulverized coal will be blown back to the grinding plate for grinding, and qualified pulverized coal will flow out of the mill with gas, and then collected by dust collection equipment to become finished products.
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.
After-sale service
We have a long-term service in the production line, good technology, responsible after-sales service team.
