Ball Mill Working Principle: Add balls into the ball drum to approximately 33%. As the ball mill rotates, the balls 'stick' to the inner surface of the ball drum due to the centrifugal force and are lifted on the rising side. At a certain angle, balls cascade down to the centerline of the ball mill because gravity overcomes the centrifugal force.

The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry.

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
