ABSTRACT:
A two-stage static air classifier has a feed duct through which particles of a granular mixture fall. A classifying louver plate having fins forming upwardly inclined classifying channels is fitted into a side opening in the feed duct. Particles of a set size are drawn by air suction through the classifying channels in the first stage. A separator box having an inlet connected to the outlet of the classifying channels collects the separated particles in a second stage as the entrained particles fall by gravity to the bottom of the separator box while the air streams drawing the particles through the classifying channels pass out the top end of the box. Adjustable baffle plates transversely extending through the box permit control of the quantity of fines collected with the particles at the separator box bottom. Size of the collected particles is determined by the speed of a fan at the top outlet of the separator box.
