Screening apparatus

A screening apparatus comprising:

• a frame;
• a motor assembly for vibrating said frame;
• at least one screen mounted on said frame for separating material by size, said at least one screen having an upper surface;
• and
• at least one feed device provided for delivering a liquid onto said at least one screen, said at least one feed device comprising a chamber provided with at least one inlet for receiving a liquid having particles of solid material entrained or suspended therein and at least one outlet for delivering said liquid and solid mixture onto said upper surface of said at least one screen;
• said at least one feed device comprising a hollow box-like structure defining said chamber, said box-like structure having a lower wall, an upper wall, a front wall, a rear wall and opposing end walls, wherein said at least one outlet is defined adjacent an upper end of said front wall;
• wherein said at least one outlet is positioned adjacent said upper surface of said at least one screen, said at least one outlet defining an elongate slot through which the liquid is constrained to pass, and wherein said at least one outlet is operable to deliver the liquid onto said upper surface of said at least one screen in a direction substantially parallel to said upper surface and to thereby establish a laminar flow of liquid and entrained or suspended solid material over said at least one screen;
• and
• wherein an upper lip of said elongate slot is defined by said upper wall with a distal edge portion of said upper lip being inclined downwardly towards said adjacent screen.
