Abstract:
A trommel for classifying objects, the trommel comprising a distal drive plate and an opposed proximal feed plate, a first plurality of first spaced longitudinal members extending between the distal drive plate and the proximal feed plate and forming an open cylinder, a member support ring disposed within the open cylinder, the member support ring having an interior periphery, a second plurality of second spaced longitudinal members having distal ends and proximal ends extending between the member support ring and the proximal feed plate respectively, the proximal ends of the second spaced longitudinal members in fixed contact with the proximal feed plate and the distal ends of the second spaced longitudinal members in a free, unattached, and unrestrained floating relationship with the inner periphery of the member support ring so as to move in essentially infinite degrees of freedom, the proximal feed plate and the member support ring forming a classifying zone therebetween, and the member support ring and the distal drive plate forming a discharge zone therebetween.
