 Leading design innovations for reliable, efficient solid/liquid separation.  

Optimised separation industrial centrifugal decanters

Multotec’s industrial centrifugal decanters enable fast and accurate centrifugation in mineral processing. They operate on the counter-flow principle. Suspension is introduced to the centre of the bowl for separation. Sediment is then conveyed via the scroll, which continuously rotates at an altered speed to that of the bowl, resulting in clarified liquid flowing from the bowl’s large diameter opening.

The range includes the TS Industrial Decanter Centrifuge, DZ Industrial Decanter Centrifuge and DZS Screen Decanter Centrifuge. All of these centrifuges:

  • reduce thermal drying and other processing costs
  • increase separation efficiency for particles of all sizes
  • have a compact design that facilitates use in small operating areas
  • reduce waste with optimised separation

 Multotec supports your requirements for customised solid/liquid separation equipment.
