Energy efficiency. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century. Traditionally the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling.

In order to convert 100 percent of kinetic energy into mechanical energy, the wind turbines will have to harness all the wind that it is subjected to. If stalwarts of the field are to be believed, these wind turbines can only convert 50 percent of the kinetic energy of the wind and convert it to mechanical energy, while the remaining 50 percent escapes the turbines.

Optimization of mill performance by using online ball and pulp measurements. In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs.
