As for one ball mill grinder, when processing one mineral, the influencing factors of grinding efficiency include property of grinding media, matching of grinding media, filling ratio of grinding media, ratio of grinding balls to materials, grinding density and feeding granularity.

Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process.

2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge. This energy is required to cause grinding of the material in the mill.

The relative 'efficiency' of horizontal grinding mills compared to other comminution equipment is often debated, and efforts to improve the energy efficiency of these mills is an on-going area of attention for process engineers. The discharge arrangement design affects the material transport characteristics within a horizontal grinding mill.
