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 ...

It was, however, found that the respective laboratory scale reflux classifier that was designed and built was not suitable for continuous operation.
In this paper, a novel reflux classifier (RC) experimental equipment was designed in which the cross-sectional area of the inclined channel is smaller than that of the vertical portion. As the rising water entered the inclined channel, its velocity increases, leading to a higher shear rate. A series of particle fractionation experiments were ...
