Abstract
A screen deck for a vibrating screen apparatus is provided with a plurality of removable and interchangeable modular screen panels, including wire screen panels having pre-crimped screen wires pretensioned in both directions. The invention contemplates the use of interchangeable wire screen panels alone or in combination with polyurethane or rubber screen panels, and provides a screen deck that can be serviced relatively easily at relatively low cost.
