SAG mills on the other hand have steel balls as an added grinding medium. As these mills grew in size and number, so too, did the enormity of the linings required. This increase in liner size created a maintenance problem, because the changing out of worn liners was a task that required specialized equipment.

Let's compare! Rubber Liners are better for abrasion grinding ie: cascade action but not for cataract mills. The graph below shows the increased operating cost of rubber and steel liners as the grinding ball size increases. Larger mill, larger ball. increases the cost benefit of using steel only mill liners. Looking at this chart, any time ...

Grinding mill liners protect the mill shell from wear and transfer energy to the grinding charge. A careful balance between liner thickness and occupied mill volume is required. Even though there are other lining materials to choose from on the market, metallic liners have proven to be the trusted workhorse for many miners. ...

Highlights Oneway coupled SPHDEM models can predict the flow of solids and fluid charge in SAG mills. End walls and worn shell liners create significant axial flow and recirculation in a SAG mill charge. Slurry flow through the grate and along the pulp lifters and discharge from the mill can be predicted. End wall lifters are critical to grate flow producing nonuniform flow through ...
