Abstract

A media recovery hopper which lies on a floor permitting spent media and debris to be swept thereinto. The hopper, in the preferred embodiment, is a substantially rectangular box having one of its four side walls shorter than the rest. The media/debris is swept over this shorter side wall while the other walls collect and "queue" the mixture for recovery. The mixture falls through a screen and into a channeling mechanism composed of a series of ridges and valleys. Along each valley are drop-orifices which permit the media/debris mixture to fall therethrough and into an air-stream which carries the mixture to proper collection or sorting mechanism.
