Joe M. Bonem, in Chemical Projects Scale Up, 2018 Solid–Liquid Separation. Although not every chemical engineering process utilizes solid–liquid separation, many of them do. Examples where solid–liquid separators are used consist of polymer production, waste treatment facilities, water purification, lubrication oil production, production of oil from oil sands, and removal of color bodies.

Spiral Classifier for Mineral Processing

 · Spiral Classifier for Mineral Processing. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn''t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.
