Introduction :Ball mills consist of a kind of rotating drum driven by an electric motor through a reduction gear. Inside of the drum the target material is arranged together with numerous steel balls (Figure 2), so that the comminution takes place due to the impacts and friction between those two components. Fig. 2. Top: Inside view of the rotating drum of a
