  • Ball Mill Finish CalculatorMartin Chick Associates

    The Ball Mill Finish Calculator can be used when an end mill with a full radius (a ball mill) is used on a contoured surface. The tool radius on each side of the cut will leave stock referred to as a scallop. The finish of the part will be determined by the height of the scallop amd the scallop will be determined by the stepover distance For example grinding with planetary ball mill makes a wide PSD which is not desired.

  • Calculate Ball Mill Grinding Capacity

    The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill The geometry of a mill with conical ends is shown in Figure 8.6.
