ABSTRACT:
A vibratory conveying and separating apparatus and a clamping device therefor are disclosed. The apparatus includes a conveyor bed which supports processing screens which convey and separate material being processed. The bed is vibrated in a forward and upward direction at a predetermined forward and upward angle of inclination. At least one releasable clamping device engages between the conveyor bed and processing screen to provide a releasable clamping force against the screen for clamping it to the conveyor bed. The clamp is mounted or positioned to orient the releasable clamping force substantially parallel with the predetermined forward and upward angle of inclination.
