  • 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 In this module, you will learn how to characterize the performance of ball mill circuits. Specifically, after completing this module, you will be able to • List and describe the four elements of the functional performance equation for ball mill circuits. • Define and calculate the classification system efficiency of a ball mill circuit.
