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 are nonlinear or have paradoxical effects on the end results. In ball milling of dry solids the main independent ...

The Effect of Ball Size Diameter on Milling Performance The Effect of Ball Size Diameter on Milling Performance

The Effect of Ball Size Diameter on Milling Performance

Ball mills are one of the most commonly used milling equipment in minerals processing due to the extensive size reduction (reduction ratio) they can achieve [2]. It is however widely determined that ball mills have very low efficiencies in terms of the utilization of the generated energy towards milling. Approximately only about 20% of the energy generated by the mill is utilized for actual ...
