Alpine SO Super Orion Ball Mill | Hosokawa Micron Powder Systems

Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out. Mills of 2 m in diameter therefore rotate in operation at about 23 revolutions per minute, which corresponds to a peripheral speed of 2.4 m/s. A mill of this size.

Different Types of Ball Mills

Wet Type Ball Mill, To grind raw material with water together. It is necessary to dehydrate & dry wet material at the later process.
