Abstract
A classifier for classifying particulates entrained in a flowing stream of gas is configured such that a change of direction of gas flow causes particles to impinge upon a target, heavier particles being trapped in a downwardly extending fluidized trap. The classifier is easily constructed, has no moving parts, and can take the place of sifters and other equipment traditionally used for classifying such product streams.
