ABSTRACT:
There is disclosed a screening apparatus for screening particulate material and which comprises a base frame, an elevating conveyor adjustably mounted on the base frame and arranged to convey material from a loading station at or near a lower end of the conveyor to a discharge station at an upper end of the conveyor, a sub-frame adjustably mounted on the base frame and carrying a vibratory screen for receiving material falling from the conveyor, a drive mechanism for adjusting the position of the conveyor along a guided path of movement, and a coupling arrangement which couples the conveyor and the sub-frame together in such a way that adjustment of the position of the conveyor relative to the base frame is accompanied by corresponding adjustment of the position of the sub-frame relative to the base frame so that the vibratory screen can take up any required attitude to suit particular requirements and in which it is still able readily to receive material falling from the upper end of the conveyor.
