I have not found the Bond models for mill liner wear to be useful and it's normal to assume a certain number of liner change outs per year, and factor this up and down depending on generalized assessments of the wear environment (consider ore hardness, feed size, ball size/surface area, abrasion index, mineralogy and water quality). I can email a copy if the paper if you don't have access to ...

TECHNICAL NOTES 8 GRINDING R. P. King · Fichier PDF

Liners protect the outer shell of the mill from wear - liners are renewable. 2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge. This energy is required to cause grinding of the material in the mill ...
