Attrition Crusher,Attrition crushing Machine for Sale

Attrition is a term applied to the reduction of materials by scrubbing it between two hard surfaces. Hammer crushers operate with close clearances between the hammers and the screen bars and they reduce by attrition combined with shear and impact reduction. Though attrition consumes more power and exacts heavier wear on hammers and screen bars, it is practical for crushing the less abrasive materials such as pure limestone and coal.

Hammer Crusher

Attrition crushing is most useful in the following circumstances:
1) When material is friabl e or not too abrasive.
2) When a closed-circuit system is not desirable to control top size.

when a Non-Reversible Hammermill is used for reduction, material is broken first by impact between hammers and material and then by a scrubbing action (shear and attrition) of material against screen bars.
