19/6/2015· 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.

ball mill initial charge Pixie Caterers. The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%. More

The second one is for calculating the surface finish of a normal ball nose end mill. If you used the first calculator you would put the diameter that it gives you and use it as the diameter in the second one. The real beauty of the second one is that if you input a diameter and surface finish, it will inversely calculate the step over for you.
