ABSTRACT:
The present invention relates to a method and apparatus for separating trash from irregularly-shaped clusters of material containing trash, fiber motes, and cotton lint. The apparatus comprises a rotatable drum encircled by a screen on an inside periphery thereof. The drum contains a plurality of finger-shaped baffles arranged in rows and extending radially inwardly from the inside periphery of the drum. As material is delivered to the rotating drum, the finger-shaped baffles lift the material toward an upper portion of the drum and drop the material directly on the screen at a lower portion of the drum to break-up clusters of material and to separate the heavy trash. The heavy trash drops through the screen and is removed by a conveyor. The fiber motes and cotton lint, along with smaller trash, are retained within the rotating drum and removed at an outlet end of the drum. The present invention also provides a clearing arrangement preferably in the form of an elongated brush contacting an outside surface of the screen. The brush operates to remove fibers and/or other material from openings in the screen.
