A system for measuring volume flow of a material includes: an imaging receiver for receiving images of a screen deck of a vibratory shaker from an overhead position; at least one illumination device for projecting a line of light onto the screen deck from an angle different than a viewing angle of the imaging receiver to the screen deck; and a mounting bracket for holding the imaging receiver and the at least one illumination device in a substantially fixed relative position to one another and to the screen deck. The system is determines the volume flow of the material based on the images of the screen deck.

Disclosed embodiments include a removable support structure for a vibratory screening machine. 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 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, made of a flexible material, provides wear protection to the removable support structure.

The invention comprises a system for wet screening of oilwell proppant at the wellsite to provide a controlled and controllable amount of properly sized and screened proppant and fluid to a frac fluid blending system.

A system for processing solid and liquid waste includes a first shale shaker, a second shale shaker, a submersible pump, a centrifugal pump, a first collection tank, a second collection tank, a mud cleaner assembly, a variable frequency drive (VFD) centrifugal solid-liquid separator, and a water clarifying assembly. The first shale shaker is in fluid communication with the second shale shaker through the submersible pump. The second shale shaker is in fluid communication with the centrifugal pump through the first collection tank. The centrifugal pump is in fluid communication with the mud cleaner assembly. The mud cleaner assembly is in fluid communication with the VFD centrifugal solid-liquid separator through the water clarifying assembly. Resultantly, the system discharges a flow of usable water through the VFD centrifugal solid-liquid separator as an initial load of solid and liquid waste is inputted into the first shale shaker.

A waste sorting system (1) comprising a tank (S) for collecting recyclable material (RM) and a sorting unit (U) comprising a first sorting station (10) connected to the tank (S) through a transport device (12) of the recyclable material and a first sorting basin (14) containing a first liquid solution (L1) of given density to separate, according to Archimedes' principle, the recyclable material (RM) into a first material phase (F1) of first selection and a second material phase (F2) of first submersion; the first sorting basin (14) is delimited at the bottom by a first lower collection portion (140), the sorting unit (U) comprising first scraper means (16) associated with the first sorting basin (14) for collecting the first phase (F1) from a free surface of the first liquid solution (L1) and first wash means (18) of this first phase (F1); the first lower collection portion (140) being passed through by a first conveyor (11).

A method and apparatus for washing and grading sand includes a first grading screen adapted to separate a feed material into a fine fraction and a coarse fraction, the coarse fraction having a greater particle size than the fine fraction. A first fines separation stage including one or more hydrocyclones is adapted to receive the fine fraction entrained in water, downstream of the first grading screen to thereby remove fine contaminants. A first dewatering screen includes a deck adapted to dewater the fine fraction downstream of the first fines separation stage to provide a fine sand product, and a second dewatering screen includes a deck adapted to dewater the coarse fraction downstream of the first grading screen to provide a coarse sand product.

A slurry handling apparatus includes at least one reception hopper includes a base, a rear wall and opposing side walls, and an opening provided in the base. Slurry delivered into the reception hopper from a tanker can pass through the opening in the base, and a respective first dewatering screen having an apertured screening deck is located beneath the at least one reception hopper so that slurry passing through the opening is delivered onto the deck of the respective screen, with undersize material and water passing through the apertures of the deck to be received within a sump, and with oversize material passing over the deck to be discharged from a downstream end of the deck.

The present disclosure relates to a separator (100) and method of separating a waste stream (120) comprising liquid constituents, small-sized solid constituents and large-sized solid constituents into a first waste stream (121) substantially comprising the large-sized solid constituents and a second waste stream (122) substantially comprising a mixture of liquid and the small-sized solid constituents. The present disclosure also relates to a waste handling system (1) comprising such separator (100).

A fat screening device includes a cylinder, and a sieve basket. The cylinder includes a feed inlet, an air outlet, a bottom water outlet, and an accommodating space. The accommodating space is in communication with the feed inlet, the air outlet, and the bottom water outlet. The feed inlet is configured to receive a mixture, the bottom water outlet is disposed at a bottom of the cylinder, the accommodating space is configured to accommodate water and fat resulting from stratification of the mixture, and the bottom water outlet is configured to discharge the water. The sieve basket covers the feed inlet and is arranged separately from the air outlet. The sieve basket is configured to screen the mixture to discharge the water and the fat into the accommodating space.
