摘要： A vibratory screening machine includes a primary screening area and a pre- screening assembly including a frame and screen assemblies. The screen assemblies are secured to the frame and form a pre-screening surface. The frame is attached to the vibratory screening machine such that the concave pre-screening surface is above the primary screening area.

摘要： A gumbo separator (10) has a continuous, inclined, moving screen belt (11) which rides on and is supported by a perforated backing plate (12). The desirable portion of drilling fluids fed to the gumbo separator (10) passes through the screen belt (11) and backing plate (12) and may be further processed to remove drill cuttings. The gumbo, containing gummy hydrated clays, are conveyed off the screen belt (11) to the reserve pit. The gumbo separator (10) provides a self cleaning screen belt (11), using a counter-rotaing belt cleaning brush (21). A spray bar (22) back-washes the screen belt (11) with high pressure drilling mud to remove any gumbo lodged in the screen belt openings.

摘要： A disclosed screen assembly (500) includes a frame (504) and a tensioned molded polyurethane screen (400a, 502) attached to the frame. The polyurethane screen has openings having a smallest length in a range from approximately 0.044 mm to approximately 4.0 mm. The screen assembly is configured to be removably attachable to an attrition screening apparatus. The frame has a perimeter that is a circle, square, rectangle, triangle, pentagon, hexagon, or other multi-sided polygon, and the screen may have similarly shaped apertures. The frame includes a support grid structure bounded by the perimeter and the screen may either be attached only to the perimeter of the frame, or may be attached to the perimeter of the frame and to one or more locations of the support grid structure. The screen includes uniaxial or biaxial reinforcement members (404a) that are integrally molded with the screen, and the tensioned screen may include tension along a direction that is parallel to, or perpendicular to, a direction of the reinforcement members. A disclosed method includes applying tension to a molded polyurethane screen and attaching the tensioned molded polyurethane screen to the frame.

摘要： Disclosed embodiments include a removable support structure (414, 424, 1706, 1902a, 1902b, 2320a, 2320b, 2402, 2502, 2602) for a vibratory screening machine (100). The removable support structure is a single structure including one or more of plastic, metal, and composite materials and may be configured to provide mechanical support to one or more screening assemblies (409, 419, 1702, 1802, 2008, 2206, 2210) of the vibratory screening machine. The removable support structure may further be configured to be removably fastened to the vibratory screening machine. The removable support structure may be a single thermoplastic injection molded piece or may be a single injection molded piece that includes nylon, carbon, and graphite. The removable support structure may have a concave shape that is configured to mechanically support a screening assembly held under compression or may have a convex shape that is configured to mechanically support a screening assembly held under tension. A disclosed wear protective covering (2502), made of a flexible material, provides wear protection to the removable support structure.

摘要： Vibratory screening machines (100) that include stacked screening deck assemblies (400) are provided. The vibratory screening machines include an outer frame (110), an inner frame (120) connected to the outer frame, and a vibratory motor assembly secured to the inner frame for vibrating the inner frame. A plurality of screen deck assemblies is attached to the inner frame in a stacked arrangement, each configured to receive replaceable screen assemblies. The screen assemblies are secured to respective ones of the plurality of the screen deck assemblies by tensioning the screen assemblies in a direction that a material to be screened flows across the screen assemblies. An undersized material discharge assembly is configured to receive materials that pass through the screen assemblies, and an oversized material discharge assembly having a deflector (1902) is configured to receive materials that pass over the screen assemblies.
