    During operation, the grinding bed is drawn underneath the roller and compressed to a very hard and dense press cake (high pressure zone). Since the particles are fully interlocked in this compressed bed, not being able to rotate, a 2-body anisotropic abrasion wear mechanism is expected. The system can be thought of as limestone particles ...
