Product introduction:Double roll crusher is mainly used to crush material which is below the medium hardness, such as clinker mineral, coke, slag, shale, limestone and so on.





Introduction:
Tarzan is a big roll crusher manufacture in China which business cover jaw crusher,cone crusher,hydraulic jaw crusher,sand making machine...
Double roll crushers is one of our excellent good with stablize quality, are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The roller crushers are not nearly as productive as cone crushers, with respect to volume, and they do have a little higher maintenance associated with them. Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs.

Working Principle-double roll crusher:
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 rollers punch the particle from 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 and powder. 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.often Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roller crushers, double roll, as primary crushers, reducing the ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. (Roll crushers used for minerals and metal ores have smooth faced rolls.)
