Fundamentals
How to select an industrial centrifuge
A centrifuge should be selected from the separation duty, not from a single flow-rate value.

Pusher Centrifuge
Continuous feeding and filtration with reciprocating pushing action to move a permeable cake through successive basket sections.
Continuous filtration
What this machine is designed to do.
Free-draining crystalline solids such as selected salt and fertilizer duties, subject to particle-size and filtration testing.
- Continuous feed and discharge suit steady production.
- Pushing stroke and frequency are process variables.
- Cake washing can be included in the filtration path.
- A continuous solids route can simplify upstream and downstream interfaces.
Working principle
Feed is distributed into a rotating screened basket. Liquid drains through the screen and a cake is formed. A reciprocating mechanism advances the cake axially while the baskets rotate. Additional dewatering and washing can take place as the cake travels toward the solids discharge.
Selection boundaries
A pusher needs a cake that drains and can be transported. High fines, compressibility, unstable feed concentration or fragile crystals can reduce suitability. Neither minimum particle size nor throughput should be assumed without testing.

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.
