Parts of a Decanter Centrifuge

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 phase forms 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 solidparticles is continuously removed by the screw conveyor, which rotates at a different speed than the bowl. As a result, the solidsare 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 (VFD) in order to adjust to variation in the solids load.
