The role of mill liners in tumbling mills. Particle breakage occurs in a tumbling mill when the mass of solid particles and grinding balls is detached by gravity from the rising shell of the rotating mill and tumbles into the toe of the mill. Particles are broken in the toe by impact, abrasion and attrition.
