The two main functions of a mill liner consist in protecting the mill shell against wear and in transmitting the energy of the mill motor to the grinding charge to carry out the required size reduction in the most efficient way. For a mill liner, the design as well as the liner material are to be considered. The required movement of the mill charge to carry out effi-
parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change. • Population balance modelling was deemed unsuitable for this purpose.

Rod mill ends have plain flat liners, slightly coned to encourage the self-centering and straight-line action of rods. They are made usually from manganese or chrome-molybdenum steels, having high impact strength. Ball mill ends usually have ribs to lift the charge with the mill rotation. The ribs prevent excessive slipping and increase liner life.
Polycorp Ball Mill Liners provide long, low maintenance, service life. In addition to protecting and sealing the ball mill's steel shell, the liner imparts motion into the ball charge. Careful, intelligent, liner design can help to improve the operation and performance of grinding mills. Polycorp's Ball Mill Liners are designed and arranged so

Mill liners protect the mill shell from wear and transfer energy to the grinding charge. Careful balance is needed to optimise these differing requirements, as poor liner design has detrimental effects on milling performance – and on mill liner life. Mill liners developed by Multotec include Ball Mill Liners, SAG Mill Liners, AG Mill Liners ...
liner design purposes. Many simulation tools exist to obtain the necessary information about media trajectories. Data are used to avoid the risk of liner and ball damage by projecting balls directly on the shell liner. Figure 3b illustrates this issue. …

Most mills can be converted from metal liners to composite rubber liners. These liners combine the best characteristics of metal alloys and rubber to obtain a superior design for use in AG/SAG, grate discharge, overflow ball mills and grinding ball mills. By using special alloy steel segments moulded into rubber, composite plates
