2005-1-1 · Again, it is evident the separations produced using the pilot-scale and the full-scale Reflux Classifier are very similar. The higher E p for the full-scale RC in the finest size fraction is a consequence of having used a higher maximum density bath in the sink-float analysis, which gives rise to a higher upper limit. (Note the curve is just ...
