Abstract
A chip sorting screen utilizing a plurality of shaped wire elements sized and spaced to allow for efficient sorting of wood chips and fiber elements. The chip sorting screen includes an upper surface formed of shaped wire elements arranged in parallel relationship to define slots between adjacent shaped wire elements. Each shaped wire element is mounted to a support member 10 define an upper surface. The mounting orientation of the shaped ware element to the support members can be consistent along a screen length or alternatively, the mounting orientation can change along the screen length to selectively vary sorting performance by varying slot size along the sorting screen. A height of each shaped wire element or an angle by which a leading edge of the shaped wire element is presented to the conveying path, can be selectively adjusted to increase wood chip turbulence across the sorting screen.
