A vibrating screen is provided for separating excess water from particulate materials such as sand, gravel, iron ore, sludge or other particulate material and/or for grading, classifying or sorting particulate material by size. The vibrating screen includes a frame upon which is mounted a deck having a plurality of apertures therein, the frame being mounted on a base and being provided with vibration generating means for imparting vibration to the deck, wherein the frame includes pair of substantially parallel side walls between which the screen is mounted, each side wall including a pair of spaced apart side members defining outer faces of the side wall, at least one intermediate member being located between the side members, wherein the at least one intermediate member incorporates a plurality of apertures and/or cut-outs therethrough.

1. A vibrating screen for grading or dewatering particulate material comprising: a frame upon which is mounted a deck having a plurality of apertures or slots therein, the frame being mounted on a base and being provided with a vibration generator for imparting vibration to the deck;wherein the frame comprises a pair of substantially parallel side walls between which the screen is mounted, each side wall comprising a pair of spaced apart side plates defining outer faces of the side wall, and an intermediate plate being located between the side plates;the intermediate plate incorporating a plurality of cut-outs formed therethrough for weight reduction, wherein the material of the intermediate plate surrounding the plurality of cut-outs defines a peripheral border region and a plurality of interconnected reinforcing webs and elongate reinforcing members within the side wall, wherein at least a subset of the plurality of cut-outs have elongate shapes with longer dimensions in the direction of the elongate reinforcing members, and at least a subset of the plurality of interconnected reinforcing webs are arranged at angles to intersect the elongate reinforcing members;wherein the side plates and the intermediate plate are formed from sheet steel, the intermediate plate having a greater thickness than that of the adjacent side plates, such that the side plates define outer skins of each side wall while the intermediate plate is configured to provide structural strength;wherein the side plates and the intermediate plate of each side wall of the frame are clamped together exclusively by a first plurality of threaded fasteners extending between the side plates,wherein the side walls of the frame are interconnected by a plurality of bridge members extending therebetween, andwherein the bridge members are connected to the side walls via a second plurality of threaded fasteners. 2. A vibrating screen as claimed in claim 1, wherein the plurality of cut-outs comprise over 50% of the surface area of the intermediate member. 3. A vibrating screen for grading or dewatering particulate material, the vibrating screen comprising: a frame upon which is mounted a deck having a plurality of apertures or slots therein, the frame being mounted on a base and being provided with a vibration generator for imparting vibration to the deck;wherein the frame comprises a pair of substantially parallel side walls between which the screen is mounted, each side wall comprising a pair of spaced apart side plates defining outer faces of the side wall, and an intermediate plate being located between the side plates;the intermediate plate incorporating a plurality of cut-outs formed therethrough, wherein the plurality of cut-outs comprise over 75% of the surface area of the intermediate plate, wherein the material of the intermediate plate surrounding the plurality of cut-outs defines a peripheral border region and a plurality of interconnected reinforcing webs and elongate reinforcing members within the side wall, wherein at least a subset of the plurality of cut-outs have elongate shapes with longer dimensions in the direction of the elongate reinforcing members;wherein the side plates and the intermediate plate are formed from sheet steel, the intermediate plate having a greater thickness than that of the adjacent side plates, such that the side plates define outer skins of each side wall while the intermediate plate is configured to provide structural strength;wherein the side plates and the intermediate plate of each side wall of the frame are clamped together exclusively by a first plurality of threaded fasteners extending between the side plates;wherein the side walls of the frame are interconnected by a plurality of bridge members extending therebetween; andwherein the bridge members are connected to the side walls via a second plurality of threaded fasteners. 4. A vibrating screen as claimed in claim 1, wherein the first and second pluralities of threaded fasteners comprise threaded bolts. 5. A vibrating screen as claimed in claim 1, wherein the bridge members comprise elongate beams or tubular members. 6. A vibrating screen as claimed in claim 1, wherein the vibration generator is mounted on one of the bridge members extending between the side walls of the frame. 7. A vibrating screen as claimed in claim 3, wherein the first and second pluralities of threaded fasteners comprise nuts and bolts.
