Abstract
A classifier for particles includes a nozzle substantially in the shape of a rectangle in cross-section, through which a gas stream carrying particles to be separated flows. Finer particles exit through a slit in one side of the substantially rectangular nozzle. In alternative embodiments, more than one such slit may be provided in the nozzle, and/or the nozzle may be substantially angularly-shaped in cross-section.
