Coal Mill

Coal Mill Introduce

Coal mill is major equipment of cement plant and used for drying and grinding coal. The equipment is mainly consisted of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system. The raw material is fed into mill by feeding equipment. The hot wind enters into the mill by inlet end. As the mill cylinder rotates, the coal and hot air exchange heat in the mill. The coal is crushed and grinded in the mill. When the coal is being grinded, the powder is brought out of the mill by the hot air going through the mill.

Coal mill classification

Ball Mill is the early coal mill used in coal powder plant, there are two types, wet ball mill and dry ball mill. This type coal mill performance is rather good:the output is high,the maintenance is friendly,the operation is easy,safety control of this coal mill.

Raymond Mill is also the early coal mill, the capacity of this coal mill can be up to 6-8 t/p. The finess of the finished product can be adjusted from 100 mesh to 325 mesh according to the requirements.

Vertical Mill is the most common coal mining equipment in milling plant, so vertical mill is also called vertical coal mill, it set up the coal mill stardard. Vertical mill produced by precise control can process large quantities of materials and it features precise grinding size, and mass production.vertical mill is the most common coal mining equipment in milling plant, so vertical mill is also called vertical coal mill, it set up the coal mill stardard. It has become the favorite equipment for large enterprises.

The above are the most common grinding mills. With increasingly worsening environment, coal power plants should utilize coal more efficiently. This matters not only the profits of the power plant, but also the social development and environmental protection.

Coal mill process

Coal is mined by explosion, then crushed by coal crusher into small pieces. In this coal crushing process, several types of coal crusher are used. Jaw crusher, impact crusher, cone crusher can be used as coal pulverizer.

After crushing, small pieces of coal enter into the coal mill for grinding. Usually a complete coal milling line includes coal mill, impulse dust cleaner, piping device, cyclone collector device, classifier. The stones are squeezed by roller and ring into powder, the powder is collected by cyclone collector. In order to ptotect the environment, we also install the cloth deduster.
