MINERAL PROCESSING - Bradken. enous (SAG) grinding mills, having a significant impact on the throughput, efficiency and perfor-mance of mills. Underestimating the importance of an optimised liner design in a mill can lead to back-flow and carry-over processes which can ultimately result in high wear, poor liner life and reduced mill throughput.

Liner wear kineticsTo study the kinetics of liner wear it was found that a first order kinetics model could well be used to describe the data. The relationship is in the form of: (1) d M d t =-kM where M is the liner mass, and k is the rate constant. Upon integration and rearranging: (2) M = M 0 e-kt where M 0 is the initial liner mass.
