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.

Dependent claims

A screen module for vibratory screening apparatus including:

at least one pair of spaced apart panel support rails, each spaced apart panel support rail having rail engagement formations;
a panel frame having opposed side portions joined by opposed end portions, the end portions being configured for locating the panel frame between the spaced apart panel support rails;
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 frame engagement formations provided on upper surfaces thereof;
and
at least one pair of removable screen panels, said screen panels overlying respective panel portions and respective rails, wherein each screen panel has screen engagement formations to removably engage both respective rail engagement formations and frame engagement formations, wherein the end portions include end faces are configured to allow clipping or frictional engagement of the panel support rails of the screening apparatus by downward pressure on the end portions, wherein the end portions of the panel frame have tapered lateral end faces that engage oppositely tapered faces provided on the panel support rails, wherein the tapered lateral end faces of the panel frame are provided with engagement formations adapted to engage with complementary engagement formations on the tapered faces of the panel support rails.
