small production runs, jar mills are employed in place of ball or pebble mills. The jar mill consists of one or more pairs of motor-driven friction rolls mounted on steel frames. They are available in a wide range of sizes and types including models with variable speed drives. The mill jars are rotated by being placed on the rolls.

Figure 2 shows the active grinding area for an optimally charged ball mill. As the drum rotates, the media should ideally form a sloping pile that maintains a 45 degree angle so that there is a constant cascading of media at the surface. Because the media is falling the fastest and for the longest distance at the top of the pile, the majority

Operation aim of ball mill grinding process is to control grinding particle size and circulation load to ball mill into their objective limits respectively, while guaranteeing producing safely and stably. The grinding process is essentially a multi-input multi-output system (MIMO) with large inertia, strong coupling and uncertainty characteristics.
The grinding behavior in a ball mill has been studied mostly from the viewpoint of the effects of such main factors, as the velocity of revolution of the mill, the size of ball, and the packing ratio.
