Product Content Description:

Double Roller Crusher
The Double 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.
Double Roller crusher Applicable material:
1) Clay
2) Shale clay
3) Coal gangue
4) River silt

Double Roller 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 of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Rolls crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers, reducing the ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. ( used for minerals and metal ores have smooth faced rolls.)
