Fundamentals
Filtration versus sedimentation centrifuges
Filtration and sedimentation separate by different mechanisms.

Thickening Screen Scroll Centrifuge
A combined thickening and filtration concept that prepares the suspension before the screen dewatering zone.
Continuous filtration
What this machine is designed to do.
Duties where preliminary concentration and screen filtration need to be considered together.
- Combines concentration and filtration functions.
- Provides another option between pure sedimentation and pure screening.
- Continuous feed supports integrated process lines.
- Different stage functions can be assessed against variable feed.
Working principle
The process combines a concentration stage with a filtering stage within the centrifuge arrangement. The concentrated solids reach the screen zone for liquid removal and conveying. The selection must account for both settling behaviour in the initial section and drainage through the subsequent solids bed.
Selection boundaries
Combining two separation mechanisms does not make all suspensions suitable. Verify fine-solids loss, scroll loading, plugging risk and the quality of each liquid stream. LLWZ and LWZ designations describe different catalogue families and must not be interchanged in an order.

Questions before quotation
What determines the final capacity?
Feed properties, the required product quality and the complete operating cycle or continuous operating window. Catalogue dimensions and rated values do not replace a representative material test.
Can this be supplied as a complete system?
The scope can be discussed around feed handling, separation, washing where applicable, discharge and controls. The quotation should identify every included item and each buyer-supplied interface.
Are special materials and safety configurations standard?
They must be specified for the material, site and selected model. Ask for the exact contact materials, seals, electrical requirements and supporting documents in the proposal.
CONFIRM THE PROCESS FIT
What should the trial establish?
Agree the feed envelope, product target and complete equipment boundary. Compare alternatives if the material does not suit this principle.
