Estimate Charge Volume of a Grinding Mill (Method 1)

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 ...

The charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. When the mill is stationary, the charge volume can be quickly obtained by measuring the diameter inside the liners and the distance from the top of the mill inside the liners to the top of the charge.
