Grit Classifier System

This type of classifier constitutes Single or Double Reciprocating rake mechanism, which is ruggedly built with structural steel and is inclined at a specific angle ( Angle of Repose). An array of Linkages with Hinge Pin joints makes it possible for long rakes to give a uniform consistent raking action at a very low energy. These robust mechanism is best known for its trouble free operation for years together. The Rake mechanism facilitates higher grit removal using different Sizes i.e, 305mm, 460 mm , 610 mm , 760 mm , 920 mm in Single Rake construction while the capacity can be doubled using common drive duplex Rake. And lengths ranging from 5 Mtr to 12 Mtr based on the Inclination angle and submergence in the trough. Rake Classifiers are built over RCC or Metallic Troughs based on the application requirements.

Features: Ease of usePrecisely engineered Hassle-free functioning

GRITSEP DS Grit Classifiers consist of an inclined screw conveyor with a large volume loading and sedimentation hopper including a water inlet and outlet spout, a shaftless screw housed in a trough, a low-friction anti-wear trough liner, a trough cover, an outlet spout for solid particles, and a drive unit mounted at the outlet end.

Grit Clasifiers can be installed at the elevator discharge section to more efficiently remove organice matter from he grit. The dewatering screw consists of a rectangular water-tight tank with an automatic wash water metering device with the inclined screw discharging the washed grid into a container. The tank is built of not less than 1/4 -inch steel reinforced with structural steel provided with suitable flanged inlet from the bucket elevator,1 inch diameter wash water inlet ,steel baffle ,overflow box having adjustable weir, and suitable diameter effluent pipe. A volume of approximately 8 cubic feet in the washer tank is required for each cubic foot per hour of grit to be washed .The wash water surface and is delivered to the tank at about 5 pounds per square inch pressure.A portion of the wash water can be introduced in to the inclined section of dewatering screw by means of adjustable spray nozz

The Noggerath Grit Classifier GS has been successfully employed in municipal and industrial wastewater treatment plants for many years in processes involving the solid / liquid separation of sand /water mixtures. Our separator system has achieved excellent results for the separation of rejects within a wide range of industrial process water cycles.

Napier-Reid Ltd. Screw Grit Classifiers efficiently wash organics from grit in wastewater plants. The wash box takes advantage of the velocity of the inlet water to separate the organics from the grit and carry them over the effluent weir. The grit is further washed by paddles and process water as grit travels up the screw to the discharge outlet. A timer is supplied to control the motor & solenoid run time making the unit as efficient as possible.

Low screw rotation speed improves sedimentation and sees to conveying and discharging of de-watered grit and sand through the upper outlet. Clean water exits through the side discharge spout of the hopper.
