Classification Performance of a Novel Hydraulic Classifier
In the present research, we propose the use of a novel hydraulic classifier equipped with a W-shaped reflector to enhance classification performance. The effects of the structural dimensions of a W-shaped reflector on the flow field of a classifier and its classification performance were investigated using numerical simulations and experiments. The results …

Dewatering Screw Classifiers
Dewatering Screw Classifiers once had a wide vogue and still are used in some pulp circuits. They were more or less troublesome because solids tended to accumulate on the sloping sides, sloughed off periodically, and plugged the discharge in the apex; the sand discharged was too dilute and contained too much slime; and sand was frequently carried over …
