Teeth roll crusher is not only widely used in cement,metallurgy, chemicals, electricity, coal and other industries onthe brittle and ductile materials processing, but also used for thecrushing of minerals below medium hardness ores and rocks. That canbe used for chemical, cement, building materials and otherindustrial sectors

Working Principle of Double roll crusher:

The particles are drawn intothe gap between the rolls by their rotating motion and a frictionangle formed between the rolls and the particle, called the nipangle. The two rolls force the particle between their rotatingsurface into the ever smaller gap area, and it fractures from thecompressive forces presented by the rotating rolls. Some majoradvantages of roller crusher are they give a very fine product sizedistribution and they produce very little dust or fines. Doubleroll crusher are effectively used in minerals crushing where theores are not too abrasive and they are also used in smaller scaleproduction mining of more abrasive metal ores, such as gold. Coalis probably the largest user of  roller crusher, currently,though. Coal plants will use double roll crusher, either singleroll or double roll, as primary crushers, reducing the ROM coal.Usually, these crushers will have teeth or raised forms on the faceof the roll. (Roll crusher used for minerals and metal ores havesmooth faced rolls.)

Our vast alloy selectionprovides the opportunity to optimize service life for virtually anycrushing situation to which a teeth roll crusher can be exposed.We’ve designed and manufactured arbors and roll shell mountinghardware for specialty roll crusher projects, as well.Miscellaneous parts — such as side liners, roll scrapers, and more— are available from Columbia’s existing inventory, or are made touser specified standards.
