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.
No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.
Ball mill is vital equipment in industries viz. mineral dressing, ore processing, increase efficiency of the mill one would have to tune the rotation velocity so Based on this equation it is possible to calculate, for example, the specific energy.
