Understanding the Effects of Liner Wear on Semi

The effect of liner wear on SAG mill performance has gained much attention in recent years It is commonly observed that the three key performance criteria of SAG milling throughput power and product size all improve as the liner increase in throughput is generally ascribed to the increase in the grate apertures and the increase in mill volume due to the wear of these components

Fine Grinding With Impact Mills Chemical

· When grinding natural gypsum — which is actually soft — a few percent of quartz in the feed will make it necessary to exchange the wear plates in the mill frequently The same or similar phenomenon applies to vegetable products that are contaminated with sand In the case of especially fine feed materials harder materials can also be processed provided that the wear protection in the

The Selection and Design of Mill Liners MillTraj

Liners protect the mill shell from wear and transfer energy to the grinding charge and a careful balance is required to optimise these conflicting requirements This review serves to highlight these problems and how they can be tackled in a logical and often inexpensive manner by considering charge trajectories and liner spacing criteria in conjunction with liner wear monitoring An overview
