double roller crusher ,mining machine

Roller crusher Application:The roller crusher is of simple structure, reliable operation and low cost. It is widely used in middle and small sized mines for intermediate and fine crashing of the brittle and soft ores of intermediate hardness like coal and coke.

Roller crusher Applicable material:
1) Clay , 2) Shale clay , 3) Coal gangue , 4) River silt

Roll crusher Working principle:

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
