Decanter Centrifuges

The Decanter Centrifuges are designed to perform separation operations for mixtures having high solid concentrations (up to 30%). The particule sizes that can be extracted varies from 2 µm to 40 mm.

E2SE distribute, in partnership with Spomasz, a wide range of decanters, including different sizes and parameters that can be adapted to your specific needs. 

For more information about our decanters, please consult the Decanter Centrifuges Product Sheet.

Working Principle

  1. The feed solution is introduced into a cylindrical-conical bowl which is rotating ;
  2. The mixture is then accelerated at high speed and divided into different phases by centrifugal force ;
  3. The solids are accumulated on the bowl walls and evacuated by a screw conveyor, which rotates at a differential speed ;
  4. The clarified liquid flows in counter-current and is discharged by overflow.

It’s possible to monitor the dryness by modifying the differential speed and consequently the retention time of the solution inside the bowl.
