2006-4-28  A video capture method has been used to study radial mixing kinetics in a dry batch ball mill. Experiments were conducted in a ball mill with PVC plastic powders being used as particles so that the effect of size reduction could be neglected. Radial mixing in ball mills was studied at typical industrial speeds of 75%, 80% and 90% of critical.

Ball Mill Loading - Dry Milling - Paul O. Abbe

The starting point for ball mill media and solids charging generally starts 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 10%-15% above the ball

In-situ monitoring of axial particle mixing in a rotating ...

2008-8-1  Austin et al. , in a slurry ball mill, found that the rate of axial dispersion was constant along the axis of the drum. In addition to mixing due to random particle dispersion, segregational effects can also occur in rotating systems when there are differences in the physical properties of the particles.

1998-6-1  Similar to experiments with 60-pm and 600-pm particles (Wightman et al., 1995; Wightman and Muzzio, 1997), axial mixing is again enhanced by rocking. Experiments for R = 2 with 60-pm and 0 = 1.8 with 600-pm particles resulted in significantly faster mixing than for R = 1with both types of particles.

The particle flow in rotating drums displays complex dynamical behaviour, and exhibits different regimes under different conditions. The mixing of particles is influenced by various parameters such as the static and dynamic angle of repose, granular shape, size, density, poisons ratio, shear/young’s modulus, coefficient of restitution and filling fraction [11,14,15,16,17,18].
