Energy efficiency - IsaMill™ Advantages Isamill. The high energy efficiency of stirred mills compared to ball mills is well understood. 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.

Energy efficiency - IsaMill™ Advantages | Isamill

Traditionally the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling. However by far the most important factor for fine grinding is media size and therefore the breakage rate. Small media has a larger surface area which translates to better transfer of energy.

Factors Affecting Ball Mill Grinding Efficiency

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this ...
