Abstract

A particle classifier comprising a casing, at least two separating wheels, a guide baffle, and a discharge conduit. The casing has a classification chamber and one or more openings that are provided to conduct air and particulate material into the classification chamber and to discharge course particles therefrom. The separating wheels are mounted in the classification chamber, and each wheel includes a multitude of blades forming openings for conducting fine particles into the interiors of the separating wheels. The guide baffle conducts air and particulate material entrained therewith upward to the separating wheels. The discharge conduit conducts from the separation chamber fine particles passing between the blade of the separating wheels.
