Abstract: A sieve bend can include a support structure supporting a screening arrangement. The screening arrangement can include a first screening segment having a first screening element configuration and at least one further screening segment having a second screening element configuration different from the first screening element configuration.

Abstract: 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.

Abstract: A separation panel includes a body member defining a separation surface and an opposed surface with a plurality of apertures extending through the body member and opening out into the separation surface and the opposed surface of the body member. The body member is made up of a plurality of discrete elements secured together to form substantially hexagonal apertures. A securing arrangement secures the discrete elements together.

Abstract: A screen includes a support structure. A plurality of screening elements is arranged in spaced relationship on the support structure to define screening apertures between adjacent screening elements. Each screening element defines a screening surface, respectively. The screening surface of each of at least some of the screening elements are spaced further from the support structure than the screening surface of each of the remaining screening elements so that, on opposed sides of each screening aperture associated with the at least some of the screening elements, the screening surfaces are at different heights.
