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.

The screen decks include an upper deck, an intermediate deck below for receiving under-sized material from the upper deck, and a lower deck below the intermediate deck for receiving under-sized material from the intermediate screen deck. A first chassis-mounted stockpile conveyor receives over-sized material from the lower deck, a second chassis-mounted stockpile conveyor receives over-sized material from the intermediate deck, and a third stockpile conveyor receives over-sized material from the upper deck. A transfer conveyor is operable to deliver over-sized material from the discharge end of the upper deck onto the third stockpile conveyor.
A screening apparatus for grading particulate material includes a grading screen having apertures for water and/or undersize particles to pass through. The grading screen is supported on a frame mounted on a chassis via resilient linkages, and the grading screen being vibrated by a vibrating device that imparts circular or reciprocating motion to the grading screen. The grading screen is set at a predetermined slope whereby material to be graded can be delivered onto an upper end while the grading screen is vibrated to convey the material over the grading screen and to cause undersize material to pass through the apertures. Oversize material is discharged from a lower end of the screen onto a conveyor or into a collection bay or hopper. A sump beneath the grading screen receives under-sized material passing through the grading screen, and a jet pump conveys material from the sump to a dewatering screen.

METHOD AND APPARATUS FOR SEPARATING SOLIDS FROM A LIQUID SUSPENSION THEREOF
A method of separating solids from a liquid suspension thereof comprising the steps of adding a flocculating agent to said liquid having solids suspended therein, introducing said liquid into a vessel having a curved peripheral wall, imparting a rotation to said liquid within the vessel whereby the flocculated solids are moved to said curved peripheral wall by centrifugal action, said solids moving down said curved peripheral wall to a lower region of the vessel under the action of gravity such that said solids collect in a lower region of said vessel, removing said liquid from an upper region of the vessel and removing said collected solids from a lower region of the vessel.
