Wear Reducing Effect of Embedded Quartz Abrasives in Crushing-Pin-on-Disc Procedure

Crushing of minerals involves several wear mechanisms. The mineral medium increases the complexity of the wear process by introducing many new variables. Despite the fact that processing of minerals normally causes wear, the minerals can also in some cases decrease the extent of wear. The comminutio...
