Mill liners need to protect the mill shell from damages due to wear and transmit the energy from the rotating mill to the ball charge. The rules that guide the design of a liner depend on the grinding mechanisms required for the specific mill. They can be classified either as impact/cataracting for very coarse to coarse grinding, cascading for ...
