A high-quality coal mill can effectively solve the fineness problem of coal powder and ensure uniform grinding of raw coal. The fineness of pulverized coal has a great influence on the ignition temperature and burning time of the equipment. In this way, the influence of bad raw coal on combustion efficiency can be well improved by coal mill.

In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.

Coal grinding mill is a machine that crushes and grinds coal into pulverized coal. It is an important auxiliary equipment of pulverized coal furnace.
