Core Technological Innovations of Decanter Centrifuges
1. High-Speed Separation and Differential Speed Control
Traditional separation equipment often relies on static filtration or sedimentation. However, decanter centrifuges utilize a high-speed drum and a differential-driven screw conveyor to achieve solid-liquid separation in seconds. The latest generation of differentials utilizes intelligent variable frequency control, automatically adjusting the speed based on material characteristics to ensure separation accuracy and solids dryness.
2. Upgraded Wear- and Corrosion-Resistant Materials
For complex, highly abrasive and corrosive materials, we utilize a variety of composite materials, including tungsten carbide spray coating, alloy overlay welding, 316L stainless steel, and duplex steel, on the drum and spiral blades to significantly extend equipment life.

Decanter Centrifuge Selection Guide
Different material properties can significantly impact equipment requirements. Key considerations for selection include:
Processing capacity: Select a centrifuge with an appropriate diameter-to-length ratio based on daily processing volume.
Solid properties: Particle size, abrasiveness, and corrosiveness determine the equipment material and wear-resistant coating.
Separation accuracy: Different requirements for liquid clarity and solids dryness require corresponding speed and differential configurations.
Operating environment: Continuous operation and high-temperature and high-pressure operation require specialized design.
