Working Principle of a Tubular Centrifuge
A tubular centrifuge is a high-speed, continuous, and precise separation device. Its operating principles can be summarized as follows:
Feeding Process
Material continuously enters the drum, typically a slender vertical cylinder, from the feed inlet.
High-Speed Rotation Separation
The drum rotates at an extremely high speed, generating a powerful centrifugal field. This force causes the material to separate into separate layers:
Higher-density solids or liquids are thrown toward the drum walls;
Lower-density liquids accumulate in the center.
Separation Types
Solid-Liquid Separation: Solid particles are deposited on the drum walls, and the clarified liquid is discharged from the top.
Liquid-Liquid Separation: Two liquids of different densities separate into separate layers within the drum and are discharged through different outlets.
Solid-Liquid-Liquid Three-Phase Separation: Solids are deposited, and the light and heavy liquids are collected separately.
Shutdown and Deslagging
Solids must be manually cleaned after shutdown to ensure high speed and stability within the equipment.
Core Advantages of Tubular Centrifuges
Ultra-High Speed
The drum speed can reach 15,000-20,000 rpm, with centrifugal forces exceeding 16,000 g, far exceeding those of standard decanter or disc centrifuges.
High Separation Precision
Effectively separates tiny particles with a diameter of 0.5 micron or greater, achieving exceptionally high liquid clarity, making it particularly suitable for applications requiring high purity.
Suitable for a wide range of materials
Not only can it perform solid-liquid separation, but it can also achieve liquid-liquid and three-phase separations, extending its applicability.
Small Footprint
The compact design occupies a significantly smaller footprint than other separation equipment of similar processing capacity.
Easy Operation
The simple design allows for easy maintenance and stable operation, requiring minimal operator training.
Low Operating Costs
Due to its high speed and efficiency, the equipment reduces repeated separation steps, saving energy and labor costs.
