2010-12-1  Grinding elements start their free flight after the point of equilibrium in a parabolic track until they hit the mill shell. In this type of study parameters such as liner profile, friction forces and interaction of grinding elements are ignored. Powell (1991) has analyzed the charge motion in detail. He applied dynamics principles to determine

2018-11-27  Correct mill liner design can affect the efficiency and the life expectancy of a mill. Some of the most commonly seen problems in these machines are premature wear and shell damage caused by impacts of the charge on the liner. Such issues could lead to early failures and shorter equipment life.
