The Selection Design and Application of Mill Liners for ...

Protect the outer shell of the mill from wear and damage Enhance the efficiency of the grinding process Need to be replaced regularly Steel liners advantages – Cope with variety ores – Superior large AGSAG ball mills – Robust application Rubber liners advantages — Softer ores — Less noise — Ease of replacement

TECHNICAL NOTES 8 GRINDING R. P. King

1. 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.

How to Control the Ball Mill Noise? - JXSC Machine

Semi-autogenous grinding (SAG) mill liner design and ...

SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance i.e. the impact of shell liners on the grinding action and of grates ...

Mill power draw models -

The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. All models generally assume that a mill is fitted with efficient liners and that the grate design neither limits passage of pebbles and pulp nor permits re-circulation of pulp back into the mill.
