Grinding ball | Magotteaux

Critical Speed and a Grinding Ball. For the ball mill to work properly, it must reach critical speed. This is the speed at which the grinding balls start to spin along the ball mills' interior walls. If the ball mill does not reach critical speed, the grinding balls will stay at the bottom. They won't be able to grind the material properly.

Ball mills may be ...

Principles of Grinding in Ball Mills

The most desirable angle to accomplish this falls between 50 to 60° from horizontal. The lower end of this range applies to wet grinding applications for soft materials. The higher break point is reserved for harder wet grinding materials such as enamel as well as dry materials. This angle of break is also determinate upon the size of the mill.
