Double Roller Crusher Usage and Application
The double rollers crusher is widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, metallurgy and so on. It can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, and so on.

Working principle of good function 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 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, such as gold. Coal is probably the largest 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.)

Features of good function roll crusher:
1.Strong crusher power and high crushing ratio, without over-crushed phenomenon
2.Crushing grades have coarse and medium crushing
3.High strength alloy steel shafts
4.Replaceable wear part design, crusher teeth can be replaced quickly
5.Unique tooth designs to allow maximum utilization of the materials
6.Grease lubricated bearings usually fed by automated system
