Effects of grinding media shapes on load behaviour

2006-11-1  It was also observed that mill power was sensitive to grinding media shape used. Power increases to the maximum with increasing mill speed for all media shapes studied. The maximum power draw for cylpebs media occurs at a relatively lower speed in comparison to the other media shapes studied. At lower speeds, cylpebs media draw more power followed by worn balls and lastly spherical
