Ball mills operate on the principle of impact and attrition: in the operation of the mill, the grinding media in the mill throw itself against the material to be ground to produce fine particles. This process is used to reduce the size of the ore to the necessary extent before proceeding, for instance, to flotation or magnetic separation.
