Krettek Separation horizontal peeler centrifuge: More Process-Equipment than dewatering device. Six step Course of Excellence, STEP 4 Resuspending and dissolving

28. May 2021

In Step 3 we explained you the unbeatable centrifugal Counter current washing
The Krettek Separation ProCent® Turbo series is not only best in class peeler centrifuge for solids-liquids separation: The unique Krettek backflushing rotor as the key-element in a complete system offers much more than just centrifugal filtration of finest particles with maximum results at minimum effort.
The special design and various options allow complete process steps inside the equipment, without additional external vessels, components, … such as:

Today’s topic: Resuspending and dissolving:

Resuspending and dissolving inside a peeler centrifuge is a feature, only possible in Krettek Backflushing Rotor Centrifuges.
Where-ever a solid product suspended in slurry needs not only mother liquids-removal but also resuspension or dissolving after mother liquids-removal the Krettek Separation Technology provides the best in class solution.
The unbeaten high g-forces in combination with the wide choice of filter media generates in first step the maximum possible dewatering.
In second step a resuspension- or dissolving-liquid is fed to the machine from Backflushing-Feeding and spray-nozzles. Since at the same time the filtrate-Skimmer is in home-position the cake can be resuspended or dissolved by a freely adjustable infinitesimal contact time, while keeping the g-force at an useful level.
The resuspended ore dissolved solids can be skimmed of by overflow-skimming-device while being feed continuously via backflushing-pipe.
Since all those steps are set once and controlled automatically from PLC the system can be freely optimized for each individual washing-system.
