In batch tests with graphite, 2 min. were required to produce a maximum shift towards larger particle sizes in the distribution curves for a stirring speed of 21,000 rpm, slurry concentration of 2 wt%, and oil dosage of 10 v/w%. For a stirring speed of 650 rpm, 4 min. were required for the maximum shift. When the oil was pre-emulsified and then added to the slurry, the maximum shift required 1 min. at 650 rpm. In all these cases, the distribution curves showed particle size reductions after their maximum shift. In the case of 650 rpm, the shift ...
