Roller Crusher - Adjustable Discharge Granularity, Low Operational Costs | Reliable Crushing For Brittle And Tough Materials

These Roller Crusher works reliable, simple maintenance and operation cost 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 Roller Crushers:
A Roller 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.

Characteristics :
a. Large feeding granularity. The discharge granularity can be adjustable automatically. And it can crush all materials which anti pressure is less than 160 MPa.
b. Even granularity, low production cost.
