study on theperformance of ball mill with liner structure

The breakingperformanceof the hemispherical lifter and the ladder lifter was poor, because the main pattern of motion was grinding rather than impact breakage. Secondly, the effects of the height–width ratio of the rectangular lifter, the height of the lifter and the number of lifters on the working efficiency of theball millwere studied

ball mill critical speed

ABall Mill Critical Speed(actuallyball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at themillshell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside amillas speed varies. Use our online formula Themillspeed is typically defined as the percent of the Theoretical
