The power required was 0.8 I.H.P. per ton crushed in 24 hours. The capacity was 62½ tons per day for each set of 8 rolls, and the total cost, exclusive of lighting, breaking, and drying, was 3s. 10d. per ton. The crushed ore was roasted and chlorinated. The rolls have now been superseded by Krupp ball mills.
6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.
