Roller crusher introduction:
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 large 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.)
Double teeth 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.
Double Roller crusher Applicable material:
1) Clay
2) Shale clay
3) Coal gangue
4) River silt
5)coke
6)furnace clinker
Features of double teeth roller crusher:
1. Compact structure, low noise and efficient;
2. Easy to install and only need simple foundation;
3. Can adjust the pressure and size easily.
4. Self-protection, the parts can not be damaged when hard materials such as the metals goes into the crushing cavity;
5. Low cost maintenance and easy to maintain.
