Description
China Coal Grinding Mill Characteristics
1. High efficiency and large output
GRMC series coal vertical grinding mill has higher working efficiency. Compared with the same type of old vertical mill, the output increases by 20-50%, and can greatly reduce the operation power consumption of the coal mill;
2. The fineness of finished product can reach 80μmR3%
GRMC series coal mill uses the most advanced static and dynamic combined separator which has high classification efficiency and big room for controlling. Selected powder fineness can reach 0.08 mm and the residue after screening can be less than 3%, being able to meet fineness requirements of most inferior coal or anthracite in cement production line.
3. Can dry the raw coal with water moisture up to 10%
The vertical mill adopts air sweeping type operation. By adjusting the incoming air temperature and air volume, it can grind and dry the raw coal with moisture up to 10%, and solve the requirement of high moisture drying with a large amount of wind.
4.Sealed structure, energy saving and environmental protection
The unique design of seal structure makes the whole system in the state of negative pressure. In the cement production line, there is no dust, low noise, and pulverized coal is collected by an air-box type pulse dust collector special for coal grinding, dust emission concentration to meet the national standards.
5. High safety performance
The coal vertical mill adopts the temperature detection device, the on-line gas analyzer and other explosion-proof measures to ensure the safe operation of the equipment. An explosion proof valve is arranged on the upper shell to prevent the explosion of the pulverized coal in the mill and ensure the safe use of the equipment.
In the nearly 60 years of large-scale grinding equipment manufacturing experience, CHAENG has manufactured many coal vertical grinding equipment which have been adopted by a number of Chinese coal grinding production lines.
