roll crusher is shown on the ac-companying sketch. A relatively sim-ple relationship between the diame-ter of feed, the roll, and the gap be-tween them is as follows: - where R =radius ofroll(mm); d the half-gap between rolls (mm); r = the radius of feed (mm); and a = the angle of friction. This e(luation may be rear-ranged as follows: 2R + 2d Cos a = 2R + 2r. (2)

Roll crushers SlideShare

24-04-2015· The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls. Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Rolls crushers
