Abstract: A screen retention mechanism for use with vibratory separators is disclosed. The screen retention mechanism includes a structural frame mounted to a vibratory separator into which a plurality of lightweight and flexible screen elements are inserted into multiple tows of perforated screen supports. The perforated screen supports are bonded to the structural frame and are aligned parallel to the direction in which solids are conveyed by a vibratory motion. The invention further features an improved retention mechanism whereby screen elements are conveniently and selectively restrained.

Abstract: Methods of manufacturing screen elements for use with vibratory separators are disclosed. The screen elements include a curved structural frame with perforations therein, the perforations designed to maximize both open area and process liquid throughput. At least one layer of screen cloth is attached to the curved structural frame by means of fluidized powdered epoxy resin.

Abstract: A screen assembly is disclosed for use with vibratory separators. The screen assembly includes a structural frame mounted to a vibratory separator into which a plurality of lightweight and flexible screen elements are inserted into multiple rows of perforated troughs which have geometric shapes. The perforated troughs are bonded to each other and to the structural frame. The perforated troughs are aligned parallel to the direction in which solids are conveyed by a vibratory motion.
