Roller coal crusher overview

Roller coal crusher,also called double roll coal 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 roll coal crusher Performance features

1. The structure of double roll coal crusher is simple and compact, the noise is low, the efficiency is high.
2. The installation is flexible, basically needs no foundation.
3. The rollers' surface adopts anti-abrasive welding rod or exchangeable dental plate, the maintenance is simple.
4. Self-preservation ability is strong, the high-hardness materials (such as all sorts of metal block) won't break the equipment's parts when they enter the shredding breach.
5. The discharge gram size is adjustable, the minimum can reach 2-10 mm.

Roller coal 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 type coal crushers are that they give a very fine product size distribution and they produce very little dust or fines. Roll type coal 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 type coal crushers, currently, though. Coal plants will use roll type coal crushers, either single roll or double roll coal crusher, 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).

Roller coal crusher applications

Roller coal crusher, also called coal roller crusher is mainly used for the crushing of brittle mines and rocks of medium or lower rightly like sinter, coke, slag, shale, limestone. It is most suitable for the mid-crushing and fine crushing work in non-metal mines of medium and small scale and chemical industries.
