ABSTRACT:
The present disclosure 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. The drum contains a plurality of finger-shaped baffles preferably arranged in two rows disposed 180.degree. apart on the inner periphery of the drum. As material is delivered to the rotating drum, the finger-shaped baffles lift and tumble the clusters of material and pull the material apart 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.
