1.Roller Crusher Machine Introduction:

The Hengchang Double Roll Crusher is ideal for primary and secondary reduction of ROM coal, washed coal, middlings,
screenings, slag, moist clay, limestone, cement, potash, rock, sulfur, lignite, pyrite, and other materials where minimum fines are required.

2.How Roll Crushers Work

Whether the application requires a single-stage or two-stage crusher, the forces necessary to perform the crushing remain the same: a combination of impact, shear and compression. 


The impact force occurs as the material enters the crusher and is impacted by the rotating roll. Shear and compression forces occur as the feed material is pulled between the crushing plate and/or crushing
rolls.

Depending on the feed size, material is fed into the crushing chamber and encounters a single or a pair of rotating rolls. 
In this scenario, the top stage of the crusher performs the primary reduction either by crushing the material between the roll and crushing plate or between a pair of rolls.


The material is then fed directly between the two bottom-stage rolls for additional processing.
If a single-stage reduction is required, then depending on the feed-to-product-size ratio of reduction, either a Single or Double Roll Crusher can be selected.

Regardless of the crusher type selected, Roll Crushers allow for the material to fracture along naturally occurring cleavage lines, which helps with minimizing fines generation.
