Roller Crusher is a type of compression crusher, and is widely used in mining

2021-01-23

 Roller Crusher is a type of compression crusher, and is widely used in mining. The reason is because it can produce fine crushed products. The roller crusher is not as productive as cone crushers, and the maintenance is high. If the ore is not too hard, they do not have high maintenance costs.

The material is fed into the roller crusher,and the roller crushers will crush material down to a minimum particle size. A roller crusher crushes by compression, with two rollers rotating. The gap between the roller is the size of product desired.

The material falls into the gap between the rollers by their rotating motion. The two rollers force the material between their rotating surface into the smaller gap area, and it crushed by the compressive forces presented by the rotating rollers. Major advantages of roller crusher is that it produces a very fine product size and little dust and noise. Roller crusher is used in minerals crushing where the ores are not too hard and it is also used in small scale production mining, such as gold.

Coal is probably the most users of roller crushers. Coal plants use single roller crusher or double roller crusher, as primary crushers, reducing the coal pieces. Usually, these crushers will have teeth on the surface of the rollers.
