Coal Mill

Coal Mill Introduction：
Coal mill is important auxiliary equipment for coal-powder boiler, and it has three methods to crush the coal briquette and grind them into a pulverized coal，like crushing, impacting and grinding.
Air swept coal mill is a new device introduced international advanced technology. And it is the main equipment in cement plant for both drying and grinding powder. Compared with the ordinary ball mill, it has advantages of larger capacity, finer particle and bigger specific surface. Therefore, it is ideal equipment for pulverized coal preparation.

Working principle：
It mainly consists of the feeding device, main bearing, rotary part, driving device, discharging device, high pressure starting device and lubricating system.
When the raw materials are conveyed into mill by feeding device, and through wind pipe, the heat wind enters in; they will exchange the heat fully along the barrel rotation. And then, the coal will be crushed and grinded, at the same time, with the heat wind, the powder will be out by discharging device.

Features and Benefits：
1. Rational structure, high grinding efficiency.
2. Low investment, few electricity and energy consumptions.
3. Simple and safety operation, reliable and steady performance.
4. Low noise, large capacity, and high economic benefits.
