More Information
Summary:A screen includes a support structure. A plurality of elongate screening elements are arranged in spaced relationship transversely on the support structure to define elongate screening apertures between adjacent screening elements. Each screening element has a screening head defining a screening surface, the screening surfaces all being at the same height relative to the support structure. Adjacent screening elements are of different widths relative to each other with a transverse dimension of the aperture being less than a width dimension of the wider screening element. The screening head of the wider screening element is shaped to maintain a substantially constant screening aperture between the screening elements during a predetermined amount of wear of the wider screening element.
