Ball mills are devices where a product is treated by the load of moving grinding media. Basically the distinguishing features of drummills are different kinds of this treatment which can fundamentally divided into shear, friction and collision where a strict distinction is possible very rarely only. The grinding media transfers kinetic energy either from a […]
