Screen assembly
First Claim
1. A screen assembly for a material processing plant, the assembly comprising:
- a screen having a mesh for segregation of fractions of material placed thereon;
a conveyor mounted beneath the screen by a pivot connection, the conveyor having a first end and being movable between i) an operative position in which the conveyor is disposed substantially parallel to the screen or receiving material which is passed through the screen, in use, and ii) an inoperative position in which the conveyor is angularly displaced about the pivot connection before providing access to the underside of the screen; and
releasable connection means between the screen and the conveyor in a fixed position relative to the screen in the operative position, and for enabling adjustment of the altitude of the conveyor relative to the screen so as to enable the first end of the conveyor to move away from the screen to the inoperative position.

Abstract
A screen assembly 22 includes a conveyor 26 pivotably mounted beneath a screen 24 for segregation of fractions of material, for example from a mobile crusher 10. Hydraulic cylinders (not shown) are used to selectively move telescopic arms 48 (only one of which is shown in the Figures), to raise or lower the conveyor 26 between operative position and inoperative positions. In the operative position the conveyor 26 is substantially parallel to the screen 24 for receiving material which has passed through the screen mesh, in use. In the inoperative position the conveyor 26 is angularly displaced relative to the screen 24 about the pivot, to provide access to the underside of the screen 24, e.g. for maintenance purposes. Removable pins 50 are provided for releasably securing the attitude of the conveyor 26 relative to the screen 24 in the operative position.
