Clarifying Decanter Centrifuge

Since its beginnings, GN has designed, developed and produced different kinds of centrifuges for  solid/liquid and liquid/liquid separation.

GN clarifying decanter centrifuge is C series decanter centrifuge with beach angle of 20 degree. It suits for material of small particle size, low density difference between solids and liquid, moderate viscosity, moderate concentration.

The P-Series,Y-Series,C-Series decanter are interchangeable by replacing bowl assembly.Final specifications should be based on commercial and technical offer.

Customized materials of the decanter centrifuge are available for option.


                The above specification and parameters for reference only.

The beach angle of the C series clarifying decanter centrifuge is 20 degree, so the bowl cone section is short, and the straight section of the bowl is longer, it will give the bowl to have a longer clarifying section.

The rotating part of these decanter tricanter centrifuges is mounted on a compact, in-line frame, with main bearings at both ends. Vibration dampers are placed under the frame. The rotating part is enclosed in a casing with a cover and a bottom section with integrated outlets for both solids and the liquid being removed.
