In Mineral Processing Design and Operations Second Edition 2016. 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.
Supplier A salt cake was crushed initially to pass 6 mesh using a laboratory roll crusher to simulate additional crushing. Investigation of kinetics of coal based reduction of oolitic iron ore The ore and coal were both crushed to 100 passing 2 mm using a laboratory roll crusher .
Aggregate larger than 4.75 mm is returned to the roll crusher until it is all smaller than 4.75 mm. Aggregate between 600 m and 4.75 mm is sent to a fine aggregate stockpile whereas aggregate smaller than 600 m is sent to a wheeled sand washer for the removal of sludge smaller than 150 m.

Jan 01 2007 Abstract. The energy required to crush rocks is proportional to the amount of new surface area that is created hence a very important percentage of the energy consumed to produce construction aggregates is spent in producing non-commercial fines. Data gathered during visits to quarries an extensive survey and laboratory experiments are used to explore the role of mineralogy and fracture mode in fines production during the crushing
Fine material is usually defined as 38 9.5mm and less. However Superiors fine material screw washers will accept a maximum feed of 34 19mm. In addition to minor scrubbing the machinery is capable of removing clays silt and unwanted lightweight contaminants. Heavier material settles to the bottom and is augured up the tub.
