ABSTRACT:
A filtering device is provided for solid wastes which includes a rotating drum having longitudinal rows of separating holes located through its outer surface. Plates are located between these rows and extend from the drum at a predetermined height in proportion to the radial dimensions of the holes. The plates can be continuous of discontinuous and can extend either perpendicularly relative to the drum or slightly inclined relative to the drum in a direction opposite the rotation of the drum. If desired, transversely extending plates may also be employed. The plates prevents clogging due to the phenomena of winding wherein fibers exit a hole and re-enter another hole as the drum rotates.
