Abstract

A screen panel assembly includes a screen panel and a raised screen component disposed thereon. The raised screen component includes an inclined screen surface that defines a first plane oriented at a first angle relative to the screen panel and a wedge surface positioned at a back side of the raised screen component. The inclined screen surface has a front edge that is aligned with a top surface of the screen panel and is substantially perpendicular to a longitudinal axis of the screen panel, the first plane being substantially perpendicular to a displacement vector along which the screen panel assembly is accelerated by a vibratory separation device. The wedge surface is adapted to disrupt a flow path of a flow of a material mixture flowing in a longitudinal direction across the screen panel by redirecting the flow around opposing sides of the raised screen component.
