how to calculate charge volume in ball or rod mill

Mill Steel Charge Volume Calculation

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. The % loading or change volume can then be read off the graph below or

How to Handle the Charge Volume of a Ball Mill or Rod

In physics, the charge of a volume is commonly described by a quantity called the charge density or the charge distribution.When the electric field that arises from the charge distribution exhibits a volumetric symmetry, a handy relationship known as Gauss’s Law may be used to calculate the charge distribution of the volume.The charge volume of a ball or rod mill is expressed as the
