InSitu Acquisition of Grinding Parameters

With earlier planetary ball mill designs the kinematics of the mills were always perfected to ensure an optimal launching point for the grinding elements as learned from the conventional ball mills The grinding drum of a ball mill functions in earth's gravity field whereas the movement of a ball in the planetary ball mill is due to the superposition of various centrifugal and coriolis forces Get price

Rod mills how they function

Rod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1 4 to 1 6 Get price

Mineral Processing

Rod and ball mills have larger reduction ratios Because rod mills provide some internal sizing action they are commonly operated in open circuit There is an increasing tendency to use an extra stage of crushing instead of a rod mill because crushers are more energy efficient Get price
