Ball MillsA Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a ...

Ball Mill Step Over CalculatorApr 04, 2016 · Ball Mill Step Over Calculator. If you are doing 3D surfacing with a ball mill you know about step over and the scallops it leaves.
