Coal mill is mainly used for grinding coal and isn't fit for every kind materials. In more than decade years, the demand for coal is more and more. And we need more coal processed products than raw materials. The appearance of coal mill brings us a lot of interests.

The coal mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished. Process of crushing mill is the surface area of ​​the coal is crushed and its growing process. To add a new surface, molecules must overcome the adhesion between the solid, which consumes energy. Coal in the coal mill was grinding into coal, rotary rod mill, mainly through crushing, crushing and pulverization in three ways. Crushing process in which the energy consumed by most provinces. Pulverization process the most expensive energy. Various mill milling process are both in the above two or three ways, but mainly depends on what type of mill may be.

There ia a main problem that should be paid attention to. It is temperature. The temperature of the primary air flow is manipulated for controlling this temperature measured as a temperature in the mill at the exit. The primary air temperature is controlled by controlling the position of an air mixer, which mixes heated outside air and cold outside air.
