The double roller crusher is mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in the trade of cement, metallurgy, chemical industry, electric power, coal and other industrial. The crushing materials include limestone, slag, coke and coal.
  Working Principles:
   The double roller crusher uses compression, with two rolls rotating around a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product required, with the realization that the largest feeding particle can only be 4 times the gap dimension. 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.
