Forces On A Particle In Crushing Rolls

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.
