The Decanter Centrifuge is a specially developed continuous Solid-Bowl horizontal Scroll Discharge centrifuge for effective separation of slurries into liquid-solid phases/liquid- liquid-solid phases, with the application of centrifugal sedimentation principle.
A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity.When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phaseforms a concentric inner layer. Different dam plates are used to vary the depth of the liquid – the so-called pond – as required.The sediment formed by the solid particles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solids are gradually "ploughed" out of the pond and up the conical “beach”.The centrifugal force compacts the solids and expels the surplus liquid. The dried solids then discharge from the bowl. The clarified liquid phase or phases overflow the dam plates situated at the opposite end of the bowl. Baffles within the centrifuge casing direct the separated phases into the correct flow path and prevent any risk of cross-contamination.The speed of the screw conveyor may be automatically adjusted by use of the variable frequency drive in order to adjust to variation in the solids load.
