If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.

1. Overflow type: discharge ore through the hollow shaft. When the ore discharge surface is higher than the slurry surface, the finished product is discharged and the ore is automatically discharged by gravity, thus the overflow ball mill saves energy. 2. Grate discharge ball mill: the ore is discharged through the grate plate.
