Abstract: A supporting structure for different screening media on a vibrating screen is disclosed, as well as a support carrier of the supporting structure. The supporting structure is received on a vibrating screen and has a number of support carriers arranged parallel to each other and perpendicular to a number of transversal carriers. The support carriers and the transversal carriers form a grid. The support carriers have grooves at each end to be snapped on and locked on circular ribs on top of the transversal carriers. The support carriers are made of a polymeric material and are elongated elements.

Abstract: A feed and sorting device for tablets has a number of vertically extending filling tubes for tablets, and a blocking slide unit for temporarily blocking the guiding channels of the filling tubes. The blocking slide unit includes a base plate with through-openings for the filling tubes and a plurality of blocking fingers designed as integral parts of the base plate and horizontally extending into the through-openings. Each blocking finger is assigned to one of the filling tubes.

Abstract: A screen frame assembly is provided for use with a screening machine. The screen frame assembly includes first and second generally planar screen frames and a coupling between the first and second screen frames that includes a tab in the first screen frame and a receiving slot in the second screen frame. The receiving slot is configured to receive the tab and includes a centering feature for laterally aligning the first and second screen frames relative to one another. The centering feature may include a pair of opposed inwardly angled edges of the receiving slot. The coupling may include an overlap region between the first and second screen frames that is engageable to thereby permit lifting of the second screen frame by a lifting force exerted upon the first screen frame.

Abstract: A vibratory separator including a screen having a filter element and a center screen disk. The vibratory separator also including a magnet disposed on top of the center pedestal support, wherein the center screen disk and the magnet are configured to magnetically interact. Additionally, a method for replacing a screen for a vibratory separator including actuating a vibratory separator decoupler and breaking a first magnetic interaction between a first magnetic interaction surface and a second magnetic interaction surface. The method further including removing a first screen from the vibratory separator, installing a second screen into the vibratory separator, and establishing a second magnetic interaction.

Abstract: A screen element (2) of a screen (1) has longitudinal sides adapted to be arranged in a longitudinal direction of a screen frame (4) and transverse sides adapted to be arranged in a transverse direction of the screen frame (4). The transverse sides of the screen element (2) are provided with at least one projection (6) and/or at least one recess (7) for locking engagement, in a direction transversely to the plane of the screen element (2), with a corresponding projection (6) and/or recess (7) on neighbouring screen elements arranged in the screen frame (4). A screen (1) with a screen element (2) arranged in a screen frame (4) is also disclosed.

Abstract: A shale shaker or vibratory separator for treating material, e.g. in one aspect, a shale shaker for treating drilling fluid having contaminants therein, the shale shaker having a base, a basket on the base, fluid introduction apparatus for introducing the drilling fluid into the basket, screen apparatus for selectively providing screening material in or under the basket, the screening material positioned so that the drilling fluid flows onto the screening material, a primary roll of screening material, a take-up roll for receiving screening material from the primary roll, the rolls rotatably mounted so that screening material is movable, through or under the basket, and onto the take-up roll, vibratory apparatus connected to the basket for vibrating the basket, and receptacle apparatus for receiving fluid flowing through the screening material.

Abstract: Screen assemblies for a vibratory separator, the screen assemblies in certain aspects having at least two screening members, the at least two screening members connected by sewing material, and methods for making such screen assemblies.

Abstract: A new and unique design enhancement and use of directional and re-directional ribs on a solids control filtering screen, such as those used in drilling wells for hydrocarbons and other substances, in conjunction with a coordinated system of hanging such screens and directing and redirecting the flow of trapped solids over the surface of such screens, is disclosed for use with a shaker. The invention counteracts the natural tendency of trapped solids to migrate to and congregate in the lowest areas of a suspended screen and facilitates a dryer fluids discharge, as well as more effectively utilizing the available screening surface area, and therefore the invention reduces the incidence of screen wear and tearing and increases the flow rate conductants through the screen.

Abstract: A sludge drying system using exhaust air from a furnace in a direct heat, rotary drum dryer to simultaneously dry and pelletize the sludge. The dried sludge particles exiting the dryer is entrained in the exhaust air. The sludge particles are separated from the exhaust air and then classified according to size. The under sized particles are recycled back to a mixer for mixing with incoming wet sludge. The oversized particles are conveyed to a crusher or mill for reducing the oversized particles down to the desired product size. The medium-sized particles can be selectively directed to be recycled with the undersized particles or collected as product. The exhaust air is treated in a treatment section, and then divided into two exhaust air streams or portions. A first portion of the exhaust air is discharged into the environment, while the second, larger portion of the exhaust air is recycled back to the furnace to be used to dry the sludge in the drier.

Abstract: A separator for separating fibers from fines in a flow of gas includes an enclosed housing which includes a cylindrical upper section and a lower section. A screen basket is fixedly mounted in the housing, and this basket defines a screened cylindrical wall, a closed bottom, and an open top. The screen basket is positioned in the housing to define an annular chamber between the upper section of the housing and the screened cylindrical wall of the basket. A first duct is mounted to pass a first flow of gas, fibers and fines into an upper portion of the annular chamber, and is oriented tangentially to cause the first flow to swirl around the screened cylindrical wall. A second duct is mounted to remove gas and fines which have passed through the screened cylindrical wall, and a third duct is mounted to remove gas and fibers which have passed to the lower section of the housing from the lower section.
