Two Roll Crusher

THE FIELDS OF APPLICATION

Smooth roll crushers are particularly suitable for medium and fine grinding processes, demanding a strictly defined portion of fine grain and low dust content.

The Feed Materials

Raw materials, secondary raw materials and by-products such as salt/chemicals/Sugar lumps and similar products.

The 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,

FEATURES

1. 1. Compact structure, low noise and efficient;
2. 2. Easy to install and only need simple foundation;
3. 3. Can adjust the pressure and size easily.
4. 4. Self-protection, the parts cannot be damaged when hard materials such as the metals goes into the crushing cavity;
5. 5. Low cost maintenance and easy to maintain.

THE MODE OF OPERATION

The crushing rolls are driven individually and directly by means of electro-motors, counter rotating via V-belts. The material is fed into the machine by means of conveyors or vibro feeder while it is spread over the whole width of the roll. The roll diameter grants an optimum angle of entry. The careful adjusting of the roller speed towards the falling speed of the feeding material guarantees a gentle grinding process with a minimum of wear and tear.
