  • What are the Differences Between Dry and Wet Type Ball

    10-03-2021· Most of the ball mills sold on the market are wet ball mills, which have high grinding fineness and good beneficiation effect. Since the dry and wet ball mill equipment has its own advantages, we must find out the suitable grinding type that the material is suitable for so that we can ensure quality and efficiency.

    Ball Mill Finish Calculator Martin 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 between cuts.
