ROTARY SCREENING APPARATUS HAVING AN IMPROVED SCREENING CYLINDER CASING

摘要

A rotary screening device is disclosed which includes a rotating cylinder having an inlet end, an outlet end and a cylindrical wall formed at least partly from the screening surface. The cylinder is rotatably supported on wheels which are in turn mounted within a trough-shaped spray shield having sides formed from a single unitary blank of metal, and which extends about the lower radial surfaces of the cylinder wall, functioning as the screening device frame.
