Difference between revisions of "Attrition Crushers"

Attrition is a term applied to the reduction of materials by scrubbing  it between two hard surfaces.  Reducing it in size and shape. Used with friable or not too abrasive materials. Hammermills 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 increases wear on hammers and screen bars, it is practical  for crushing less abrasive materials such as pure limestone and coal.
