Abstract

A trommel for classifying and sorting objects. The trommel is an open cylinder including a drive plate and a feed plate. A series of supporting rods extend between the drive plate and the feed plate. Disposed therebetween is a rod support ring dividing the trommel into a classifying zone and a discharge zone. A plurality of vibrating rods, floating in the vicinity of the rod support ring and anchored to the feed plate, oscillate and flex as the trommel rotates causing preselected sized objects to pass through the vibrating and support bars while the remaining objects are passed into the discharge zone with reduced clogging.
