Separation and Classification of Solids | PDF | Solid
The rake classifiers have almost similar configurations with spiral classifiers. The only difference is that the rakes move following a rectangular direction in rake classifiers. Hydraulic classifiers differ from sedimentation classifiers in that particle settling directions are in opposite to fluid movement. It is a mechanical cone classifier ...
