Screen module for vibratory screening apparatus

Abstract

The invention provides a screen module for use on vibratory screening apparatus. The screen module includes: a panel frame having opposed side portions joined by opposed end portions, the end portions being configured for locating the panel frame between spaced panel support rails of the vibratory screening apparatus; at least one intermediate portion extending between the opposed side portions and/or opposed end portions and dividing the panel frame into panel portions; the side portions and said at least one intermediate portion having engagement formations provided on upper surfaces thereof that, together with engagement formations provided on each of the panel support rails of the vibratory screening apparatus, in use, form peripheral panel engagement formations about the panel portions; and at least one pair of screen panels, said screen panels overlying respective panel portions of the panel frame and including complementary engagement formations on an underside periphery thereof for engagement with the peripheral panel engagement formations, defined by the engagement formations of the panel frame and panel support rails.
