Product catalog summary
Main Applications
The decanter centrifuge is engineered for separation operations in mixtures with high solid concentrations ranging from 1% to 30%. It operates by introducing the feed solution into a rotating cylindrical-conical bowl, where centrifugal force divides the liquid into two or three phases. A screw conveyor, rotating at a differential speed, evacuates accumulated solids, while the clarified liquid is discharged by overflow. The dryness of the output can be adjusted by modifying the differential speed, affecting the retention time of solids.

Product Range
In partnership with Spomasz, a variety of decanters are available, adaptable to specific needs. Customized analysis and solutions are provided to optimize performance for different processes.

Operating Principle
The decanter uses a 2-phase separation technology. Key technical data for different models include:
  • Hydraulic flow: 12 to 50 m3/h
  • Production flow: 2.5 to 25 m3/h
  • Bowl diameter: 250 to 600 mm
  • Rotation speed: 2300 to 5000 rpm
  • Solid concentration acceptance: up to 30%
  • Main engine power: 11 to 45 kW
  • Secondary engine power: 3 to 18.5 kW
  • Dimensions and weight vary by model

Applications
The decanter centrifuges are suitable for clarification, concentration, and separation operations across various industries, including pharmaceuticals, cosmetics, food and beverage, oil and water treatment, and renewables.

Decanter Centrifuges-1

Centrifuges The decanter is designed to perform separation operations for mixtures having high solid concentrations (from 1 % up to 30 %). Operating Principle ie feed solution is introduced into a cylindrical-conical bowl which is rotating. The liquid is accelerated at high speed and divided into 2 or 3 phases by centrifugal force. A screw conveyor, which rotates at a differential speed, ensures the evacuation of the accumulated solids to the tapered outlet. The clarified liquid flows in counter-current and is discharged by overflow (cf. Separation Technology scheme). It is possible to monitor the dryness by modifying the differential speed and consequently the retention time of the solid inside the bowl. Our decanters are able to extract particles which size varies from 2 pm to 40 mm with an hydraulic outflow reaching up to 50 m3/h. WD 453 Decanter Product Range We distribute, in partnership with Spomasz, a range of decanters including different sizes and parameters that can be adapted to your specific needs.
