Modular screen system for screening deck

Abstract

A screening deck is shown and described including an intermediate frame structure mountable to the screening deck in a manner similar to that of an original screen component, but providing mounting formations for attachment of a plurality of screen modules thereon. The screening deck need not be modified in order to receive the intermediate frame. The intermediate frame may be applied to either a crowned screening deck or a flat screening deck. In the crowned configuration, the intermediate frame takes a form similar to the original screen, but includes mounting rails for receiving the screen modules. In the flat screening deck configuration, individual intermediate frame components mount along the longitudinal support beams and provide formations for mounting of screen components thereon. In each illustrated embodiment, individual screen components are mounted and dismounted without separate fastening elements and enjoy support along at least two edges thereof.
