Different sizes of ball and race mills

  • Types of Ball Mills | Our Pastimes

    Like all ball mills, the speed and ball size have an effect on how the vertical ball mill works. Vertical ball mills often come with a variety of ball sizes (and have variable speed settings) for more efficient processing. Industrial Ball Mills. Industrial ball mills are much larger than the other types of ball mills.

  • Optimum choice of the make-up ball sizes for maximum ...

    For a single size of make-up balls, the ball size distributions exhibit a mono-modal size distribution with a mode close to the original make-up ball sizes. A 1:1 mixture of two make-up ball sizes shows the bimodality of the ball size distributions, consisting of two populations derived from large and small make-up balls.

  • Rod mills, how they function - Mine Engineer.Com

    Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
