Separator Disc Stack Centrifuge For Sale

Equipment Overview

A disc centrifuge is a highly efficient fine separation device, classified as a high-speed sedimentation centrifuge. Its core structure consists of a high-speed rotating drum and multiple layers of conical discs. Under the powerful centrifugal force, materials are separated into separate layers, allowing fine particles or droplets to quickly settle, achieving solid-liquid separation or liquid-liquid-solid three-phase separation. Disc centrifuges are widely used in the food and beverage, dairy, biopharmaceutical, chemical, and energy industries due to their high separation accuracy, strong processing capacity, and compact structure.

Working Principle

When a mixed liquid enters the high-speed rotating drum through a feed pipe, it is flung toward the drum wall by the centrifugal force. Components of varying densities are separated along the channels between the discs.

Due to their high density, solid particles are deposited between the discs and the drum wall and discharged through an automatic or intermittent discharge system.

The light and heavy liquid phases flow to separate outlets, achieving continuous separation.

This disc structure significantly shortens the separation path, enabling the disc centrifuge to maintain high efficiency even when processing very fine particles (0.5-5μm in diameter).

Applications

Due to their high separation performance, disc centrifuges are suitable for nearly all industries requiring high separation precision:

Food and Beverage: milk clarification, whey separation, juice decontamination, and beer yeast removal;

Pharmaceutical and Biological: vaccine separation, fermentation broth extraction, and blood product separation;

Chemical Industry: lubricant oil purification, catalyst recovery, and emulsion demulsification;

Energy and Environmental Protection: biodiesel refining, oil-water separation, and wastewater treatment.
