The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

the ball mill mixer had a finite value of around 25 Pa even at t = 10 s. Eventually, after a long period of time, values of G* for the ball mill and the 3D mixers approached each other, while the curve for the Rushton impeller deviated further away from the others. This is consistent with the steady shear viscosity results showed in Figure 12.
