Abstract

The invention provides a vibratory screen (100) with several improvements. A side panel (160) comprises an outer carbon fibre layer (1720), an inner carbon fibre layer (1710) and a foam layer (130) between the inner and outer carbon fibre layers. A support beam (140) comprises an inner core (1420) having at least one carbon fibre layer and an outer polymeric shell (1425) formed on the at least one carbon fibre layer. A protective cover (1800) for the support beam (140) comprises a cover body (1810) and one or more deflecting elements (1820) for deflecting material away from the support beam. Other improvements include a protective plate (200) for the side panels (160) and a driver member assembly (130) having drive beams (400) with an opening (480) to relieve stress.

Abstract

The invention provides a drive member assembly (130) for a vibratory screen (100) having a frame (110), comprising drive members or beams (400) having opposed ends (410, 420) for engaging the frame. There is an opening (480), preferably curved, at or adjacent at least one of the opposed ends (410, 420) for relieving stress on each drive member (400). A vibratory screen (100) incorporating the drive member assembly (130) is also provided.
