Analysis shows the relative power inefficiency of large ball mills is due to their inefficient breakage of coarse particles. The models developed can be used to scale-up mill behavior. The behavior of large mills at Bougainville and Pinto Valley is compared.

Variables in Ball Mill Operation Paul O. Abbe®

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art it’s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables

Grinding balls are utilized in the ball mills jennifer0972 博

2012-8-20  Almost all ball mills use a form of closed circuit grinding that returns material that is too coarse back to the ball mill inlet while material fine enough to meet product requirements is collected. The separator determines which particles will be returned and which particles are sufficiently fine.
