Abstract
A system for providing a self-cleaning function to rectangular vibratory screens which may be disposed on an incline in a vibratory separating system. Pans or screens defining flow-through support surfaces span across the frame of a screen parallel and displaced from the screen cloth. Sliders are positioned on the pans which have the capability of impacting the underside of the screen cloth when the vibratory system is in motion. Dynamic mechanisms for imparting circulatory motion to the sliders include mounting rods associated with the pans or screen frame members which extend laterally across same. Tubes capable of eccentric motion about the rods are mounted thereto such that the vibratory motion of the screening mechanism induces such movement for impacting against sliders to cause slider circulation. The sides of the pans are slightly flared outwardly to engage the screen frame for proper location of the system within each screen.
