In many cases, the initial wear mechanism is adhesive, generating wear particles, which are trapped at the interface, resulting in three-body abrasive wear. Abrasive wear by plastic deformation Material removal from a surface by plastic deformation may occur in several deformation modes, which include ploughing, wedge formation and cutting.
The overall erosion wear rates in a straight section of sand slurry pipeline can be estimated if the contribution of each of the erosion wear mechanisms can be quantified. Figure 4. Simplified wear damage model of sand slurry pipeline section

Crusher . wear mechanism of jaw crusher teeth plate A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker.
Adhesion wear is a result of micro-junctions caused by welding between the opposing asperities on the rubbing surfaces of the counterbodies. The load applied to the contacting asperities is so high that they deform and adhere to each other forming micro-joints.

Wear types and mechanisms. Wear is commonly classified according to so-called wear types,  which occur in isolation or complex interaction. Common types of wear include: Adhesive wear; Abrasive wear; Surface fatigue
Jun 24, 2004· One of them is abrasive wear mechanism (cutting, plowing, chipping, etc.)due to erosion by the abrasives (stones/sand) present in the flow. There may be involvement of some kind of corrosive wear mechanism, depending on the pH and other chemical species present in water.
