bowl rake

A bowl and rake classifier is typically used to separate coarse and fine particles of granular material temporarily suspended in water.

The coarse particles settle to the bottom of the vessel and are scraped by a set of blades. The fine particles are carried over the edge of the classifier. This is how the offered rake classifier works. On the other hand, a bowl classifier, as the name implies is a shallow bowl with a concave bottom which holds the liquid solid suspension and the coarse particles fall to the bottom where they meet at a central discharge point and the fine particles overflow the edges and are collected. The offer bowl and rake classifiers are used for dewatering applications.
