Formula: step per inch = (motor steps * microstepping) / (travel at one turn of the motor in inches) if microstepping is set at 16 (1/16 on the driver) then and you are using a sprocket and chain with a pitch of .25 inches and 12 teeth on the drive sprocket. = (200 * 16) / (12 * .25) = 3200 / 3. = 1066.666 steps per inch.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

How Does ball mill Work? Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium.
