摘要： A method of treating and grading contaminated particulate material includes i. physically breaking up the particulate material to separate the particles thereof; ii. rinsing and grading the particulate material to separate the particulate material into an oversize fraction and an undersize fraction; iii. washing and grading the oversize fraction to produce one or more treated aggregate products; iv. passing the undersize fraction through a high shear washing process to separate contaminants therefrom; v. fluidising and cleaning the undersize fraction in a classification tank to produce one or more treated sand products at an underflow thereof by passing clean water upwardly into the classification tank. Optionally, waste water resulting from stages (ii), (iii) and (iv) is treated to form process water, a portion of which is used in stage (ii), a portion of the process water undergoing one or more further treatment processes to produce clean water used in stage (v).

摘要： An apparatus is provided for feeding slurry to a recycling or slurry treatment process at an elevated location. The apparatus includes a reception hopper for receiving the slurry from a transport vehicle, and a bucket elevator for conveying the slurry from a loading zone, in communication with the reception hopper, to a discharge zone at an elevated location. The reception hopper includes a trough having parallel side walls and a bottom wall. The loading zone of the bucket elevator communicates with a first end of the trough, the trough including a movable wall extending perpendicular to the side walls of the reception hopper and being movable towards the first end of the trough to urge slurry towards the loading zone of the bucket elevator.

摘要： A multi-deck screening assembly includes upper and lower screen decks, each having first and second deck sections. The upper deck's first deck section has first-size grading apertures, and its second deck section is downstream of the first deck section with second-size grading apertures larger than the first-size apertures. The lower deck's first section has third-size grading apertures and its second section is downstream of its first section with fourth-size grading apertures larger than the third-size apertures. A gap between the lower deck's first and second sections allows oversize material from the lower deck's first section to pass through to a first collection region. A diverter is positioned between the upper and lower decks and over the gap, whereby material from the upper deck collected on the diverter passes onto the lower deck's second section, thereby preventing undersize material that passes through the upper deck from passing directly through the gap.

摘要： A process for refining sand for use as frac sand includes the steps of passing the sand through a first fines separation stage to remove fine particles of contaminant from the sand, reducing the water content of the sand (such as to less than 20%), passing the sand into an attrition scrubber unit containing moving blades to delaminate clay and other contaminants from the sand grains, passing the sand from the attrition scrubber unit through a second fines separation stage to separate fine contaminants from the sand, and dewatering the resulting sand product in a further dewatering stage.

摘要： A screen assembly for grading and dewatering sand includes a frame upon which is mounted a deck having a plurality of apertures therein. The frame is mounted on a base and includes a vibration generating device for imparting vibration to the deck. The deck has a first portion inclined downwardly from a first end to second end for grading sand thereon, and a second portion for dewatering sand thereon. The first deck portion is inclined downwardly at a first angle, and the second portion is arranged substantially horizontally or inclined upwardly at a second angle. Sand may be delivered onto the deck at or adjacent the first end of the first portion, so that undersized particles of sand passing through the apertures in the first portion of the deck as oversized particles pass onto the second portion of the deck, whereby the oversized particles are dewatered.

摘要： An apparatus for processing aggregate material includes a chassis, a trough mounted on the chassis at an inclined angle, and at least one shaft rotatably mounted within the trough and extending from a lower to an upper end of the trough. The at least one shaft has blades mounted thereon, the blades being angled so that they carry material within the trough towards the upper end of the trough when the at least one shaft is in a normal direction of rotation. A discharge opening is formed in a base of the trough adjacent the upper end of the trough, a weir being provided in the trough upstream of the discharge opening over which processed material must pass to reach the discharge opening.

摘要： An apparatus for reducing the water content of waste water sludge includes a column for receiving waste water sludge, an outlet at a lower end of the column, a first closure for closing the outlet of the column, a controller for controlling the opening and closing of the closure. The controller is adapted to open and close the first closure to periodically discharge amounts of settled fines from the lower end of the column. A water outlet is adapted to receive water overflowing from an upper end of the column.

摘要： A portable waste treatment apparatus for treating hydro-excavation waste includes an elongate frame formed from separable upper and lower frame sections mounted upon one another. The upper frame section houses a mixing tank for receiving waste slurry and for mixing the waste slurry with flocculating and/or coagulating agents. A thickener tank receives waste slurry from the mixing tank, and a dewatering device is provided for dewatering sludge collected in the thickener tank. The lower frame section houses a buffer tank arranged to receive sludge from a sludge outlet of the thickener tank. A pump is provided for pumping the sludge to the dewatering device, and a water tank is arranged to receive water overflowing from the thickener tank.
