Abstract
A vibratory drum includes a tubular drum having a longitudinal axis, and first and second vibratory generators disposed laterally relative to the longitudinal axis and opposite each other across the tubular drum. The drum also includes a frame to which the first and second vibratory generators are attached; and a plurality of resilient elements attached at a first end to the tubular drum and at a second end to the frame, whereby the vibratory motion of the generators is transferred to the tubular drum to impart a circular motion to material disposed in the tubular drum.
