Abstract:
1. A device for separating and classifying particles of a homogeneous granular mixture comprising: a feed duct having a feed inlet, a particle discharge outlet, a side particle opening and a side gas inlet opening, both of which are positioned between the feed inlet and the particle discharge outlet, said gas inlet opening designed to allow gas to flow into said feed duct and to direct a portion of said homogeneous granular mixture through said side particle opening as said homogeneous granular mixture moves from said feed inlet toward said particle discharge outlet; a separator box having a top section with a dust collector outlet, a bottom section with a classifier outlet and an intermediate section therebetween, said bottom section including a particle inlet fluidly connected to said particle opening of said feed duct; a classifying louver plate positioned between said particle inlet of said separator box and said particle opening of said feed duct, said classifying louver plate including a plurality of fins defining classifying channels between adjacently positioned fins; and, a fan designed to cause a flow of gas from said particle inlet, into said separator box and upwardly to said dust collector outlet.
