Abstract: The invention provides a screening arrangement including a screen deck constituted by a non-stretchable, flexible screen cloth material defining a feed end and a discharge end. The feed end and discharge end are secured to mounting formations associated with a frame and the association is such that in use the screen deck may be reciprocated between a taut state and a slack state. The screen deck is located at an angle to the horizontal sloping downwardly from the feed end to the discharge end. The arrangement of the present invention has a high resistance against blinding of the screen deck.
