A systematic study on the comminution of a soft (coal) and a hard (iron ore) material is carried out to investigate the bulk comminution features of the hammer mill. The effect of the feed rate and the rotor speed on the mill efficiency in terms of reduction ratio, energy expenditure, fines produced and median size is investigated.
