- Conical / Cylindrical Bowl Design
In Decanter centrifuges the cleaning of liquid takes place in cylindrical part where as dewatering of solids by compression of the filter cake takes place in conical part of the bowl. The geometry of the bowl, relation with length and diameter to be adapted to suit the application. In most of the cases, good results are obtained at length diameter 2 : 1 and sometime depending upon application 2.5 / 3 : 1.
The system is continuous, compact and enclosed while offering versatility, high performance, and low maintenance.
The Decanters / Solid Bowl Centrifuges are used for clarification (liquid / solid separations), dewatering and classification duties in various process industries.
Typical products processed:
Inorganic products: Aluminium hydroxide, barium sulphate, lead oxide,
chromium oxide, ferrous hydroxide, magnesium hydroxide, titanium dioxide, zinc sulphate. etc..
Organic products : Carboxymethycellulose, caprolactam, dimethylterephthalate, terephthalic acid, phthalic acid, etc..
Plastics : Polyethylene, polypropylene, polystyrene, polyvinyl chloride, etc..
Silicates : Asbestos, clay, etc..
Cellulose: De-inking flotation concentrate
Foodstuffs: Fishmeal, casein, whey, etc..
Based on the principle of sedimentation, the Decanter Solid Bowl Centrifuge uses the force developed under fast rotation of a helical screw conveyor which separates the liquid from the solid fraction at a slightly higher or lower speed than the bowl.
