    is low, discharging particle size can be adjusted. According to the

    number of rolls can be divided into double roll crusher and four roll

    crusher, which can be widely used in cement, metallurgy, chemical

    industry, electric power, coal and other industries, the brittle and

    toughness material processing.

    Working Principle of Roll Crushers:

    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. 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.
