VIBRATING SCREEN

摘要

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, said frame being mounted on a base and being provided with vibration generating means for imparting vibration to said deck, wherein said frame comprises pair of substantially parallel side walls between which the screen is mounted, each side wall comprising a pair of spaced apart side members defining outer faces of the side wall, an intermediate member being located between said side members, said intermediate member incorporating a plurality of apertures and/or cut-outs therethrough, the material of said intermediate member surrounding said plurality of apertures and/or cut-outs defining a peripheral border region and a plurality of interconnected reinforcing webs and elongate reinforcing members within the assembled side wall, wherein said at least one intermediate member is formed from a sheet material having a greater thickness than that of the adjacent side members, such that the side members define outer skins of each side wall while the at least one intermediate member provides structural strength.
