The better mills on the market have an efficiency of about 89 % which means that only 89 % 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 ...
