When the air flow is changed, the size distribution of the coal in the mill, coal on the grinding table and coal suspended in air/coal mixture stream, is changed. With an increasing air flow, more coarse coal particles will be blown out by the stronger air flow, and vice versa. Therefore, mill level must vary with both air and coal flow input.

The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have a drying function besides grinding.
