Features and Applications of roll steel crusher:
Roll crushers have the advantage of producing an end-product that is has a fine size distribution and they produce little dust or fines during operation. They are widely used for crushing minerals whose abrasive levels are low and in the small scale production of mine. Roll crushers are mostly used during coal mining. The crushers used may either be single roll or double roll. When used in coal mining, the surface of the rolls will have teeth or raised forms (when used for minerald and metal ores, the rolls have a smooth surface).
The roll crushers are capable of producing between 100 and 120 million bricks per year. They are widely used in the production of facing bricks, paving bricks, hollow and thermal bricks.

Roller 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 roller crushers are they give a very fine product size distribution and they produce very little dust or fines. Roller 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.)
