Cadoche and López (1989) tested knife and hammer mills on hardwood chips, agricultural straw and corn stover. Energy consumption to reduce hardwood chips to a particle size of mm was 130 kWh/Mg for both hammer and knife mills. The hammer mill required more energy (115 kWh/Mg) than a knife mill (50 kWh/Mg) for mm particle size.

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.
