Separators, Classifiers, and Screeners Selection Guide

Rake, spiral, and bowl classifiers use mechanical action to dewater, deslime or separate coarse bulk materials from finer materials or liquids. 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.

Screening and Classification

Classification is also a sizing process which involves particle size as the primary physical parameter, but also is affected by particle specific gravity. It is a wet process although dry classification exists and involves a moving fluid medium which transports the particles to separate products based on size and SG accordingly.
