600–1500 L/h Disk Stack Centrifuge for Biodiesel Separation

Product introduction of Disk Stack Centrifuge

A disk stack centrifuge is a precision high-speed separation machine designed for continuous clarification and phase separation of liquid-liquid and liquid-solid mixtures. It features a vertical rotating bowl equipped with stacked conical discs that significantly increase separation efficiency and clarify surface area. The equipment is built with industrial-grade materials and supports a throughput of 600–1500 L/h. It solves challenges such as fine particle removal, emulsion breaking, and liquid purification. It is suitable for industries requiring high-precision separation, including biofuel production, chemical processing, microalgae refining, and food-grade liquid clarification applications.

Working Principle

The disk stack centrifuge operates by feeding liquid mixtures into a rapidly rotating vertical bowl containing stacked conical discs. Under high centrifugal force, heavier particles move outward while lighter liquid phases move inward and upward. The discs shorten settling distance, greatly improving separation efficiency. Solids accumulate and are discharged automatically or periodically, while clarified liquids exit through separate outlets. The system achieves continuous, high-precision separation of emulsions, suspensions, and fine particle mixtures across industrial processing applications.
