Separators, Classifiers, and Screeners Information
Drag classifiers consist of a chain-link conveyor or endless belt that is dragged through a solid-liquid mixture. Rake classifiers lift solid-liquid mixtures up onto a plate with a screen or rake. Spiral classifiers use an Archimedes pump screw to lift solid-liquid mixtures up onto a screen for dewatering.

Rake Classifier
rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …

Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the …
