#0183;#32;When the finest grinding is required by dry grinding, the jet milling or the attrition milling with a roller mill, a ball media mill or a powderbed attrition mill would be useful. Figure 10 shows a comparison of grinding performance between the powderbed attritiontype mill and an air jet mill as well as impact mills equipped with attrition mechanism.
