Comparison of energy efficiency between ball mills and ...

2009-6-1  Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills (Napier-Munn et al., 1996). At product sizes finer than 80% passing 75 μm, the efficiency of ball mill grinding rapidly decreases.

5 Best Milling Machines - Nov. 2021 - BestReviews

A good micro mill won't have the capacity of a workshop mill, but its feature set should be very similar. Power and speed. As we've already said, the forces generated by milling can be immense. As a result, powerful motors are needed. Motor power. For a mini mill, we wouldn't expect to see less than a one-horsepower motor.
