SCREENING MACHINE AND ASSOCIATED SCREEN PANEL.

摘要

A screening machine (10) of the type used to separate or classify mixtures of solid particles of different sizes includes a machine frame (20) and a perforate screen panel (28) mounted for movement relative to the machine frame (20) during a screening operation. The screen panels (28) are pre-tensioned mesh screen material (34) mounted in a peripheral rim (52) for separating various granular and particulate materials. The screen panel (28) is slid into the side of the machine frame (20) in a direction orthogonal to the direction particulate matter moves when the screening machine (10) is operating. The screen panel (28) peripheral rim (52) has a shaped or other cross section adapted to hold a large seal member that provides a positive sealing surface for contact with the machine frame (20) to prevent particulate matter from escaping off of the screen panel (28) during use.
