The test mill runs with a circumferential speed of 0.036 m/s. This is comparable with that one of the Hardgrove tester (0.08 m/s), however, much slower than the velocity in technical coal mills of about 3 to 5 m/s. And the questions arise, whether and how the breakage and the material introduction into the gap depend on the speed.

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 drying function besides grinding.
