The better mills on the market have an efficiency of about 8-9 % which means that only 8-9 % of the energy results in grinding and the majority is converted mainly into heat. The ball mill has the worst efficiency of all types of mills on the market. Just 4 % of the energy is used for comminution. Nevertheless when grinding is required the ball ...

As a rule of thumb, one should consider that the maximum particle size which would physically/effectively be nipped by the rolls would approximately be 1.75 times the size of the operating gap. Generally, depending on ore type and process conditions, the operating gap would be about 2.0–2.5% of the roll diameter.
