Effects of grinding media shapes on load behaviour and

Nov 01, 2006· This study investigated the effects of three media shapes (cylpebs, spherical and worn balls) on load behaviour and mill power draw at various mill speeds and load filling. An inductive proximity probe was used to determine the load orientation of the grinding media charge while a load beam enabled measurement of power draw.
