l. The increased use of coal by utilities which have no prior pulverized coal experience. 2. The increased use of lower rank, higher volatile content coals. 3. The increased use of control room electronic data gathering and retrieval systems which display only digital, rather than digital and analog, information.
The analysis [45] proves that the maximum capacity of the ball-ring mill is obtained using 5 or 6 balls. Because earlier, as a rule, a greater number of balls was used, there is a possibility to increase the capacity by replacing the existing balls through a lower number of bigger balls. ... B.

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.
