Mill Charge

The ball load should be 40-58% of the total internal mill volume, and the material to be ground should fill only the voids between the balls (a maximum of twice the ball space) Viscosity, the order of filler addition, and the quantity of material should be chosen so as not to cause a viscosity increase above the specified range, since the milling efficiency drastically decreases at that point
