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.
