ABSTRACT:
A vibratory screening machine for separating particles from fluid includes a fine mesh screen located within a vibratory basket. The machine further includes a supply for delivering fluid having the entrained particles from a source thereof towards the screen. A weir is disposed substantially adjacent the supply and overlies an upstream portion of the screen for directing the flow of fluid onto the screen. The weir includes an upstream end positioned adjacent the supply and a downstream end. A plate forming a dam is attached to the downstream end of the weir to form a pool of fluid on the weir. The weir includes at least one fluid flow opening positioned substantially adjacent the plate forming the dam. A flow directing plate is connected to the weir for directing the fluid flowing through the fluid flow opening towards the upstream portion of the screen underlying the weir.
