Mill liners have a dual purpose: firstly, to protect the shell of the mill from wear, and secondly to transmit energy to the charge (ore + grinding media). The design of the liner must take these two aspects into consid-eration. The optimal design is a compromise between lifetime and efficiency. Liner design The liner design has a huge impact ...

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-

components that will include KAron. Liner thicknesses normally range between 0.010 to 0.015 inches (0.25 to 0.38mm). Liner thickness is also a function of the amount of wear or clearance a system can tolerate and continue to operate as intended. For applications where clearance is not an issue, the liner thickness can be increased.
