For this reason, rolls should be worked in closed circuit with screens wherever control of maximum particle size leaving the crusher is important. Roll crushing of the sledging type have a crushing action unlike that of any of the machines …
Where, Di,max is the largest particle diameter in i th size grade and WR is the gap between rolls of a smooth double roll crusher. Equation of the process becomes: (2) p = ( π B Ω + I − π Ω) ⋅ f Alternatively, this equation can be written as, (3) ( p − f) − π ( B − I) Ω f = 0 Eq.
Working Principle of Double roll crusher A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.

Double-roll crushers are able to crush more finely than single-roll crushers, because they are designed with teeth that mesh together rather than rotating past a smooth plate. They can reduce coal to as little as ¼ inch (0.6 cm) topsize, although they are more commonly operated close to …
Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.
