Technical Features of Decanter Centrifuges
As a representative decanter centrifuge, decanter centrifuges possess the following key technical features:
High-Speed Rotation and Powerful Centrifugal Force
The bowl operates at thousands of revolutions per minute, generating centrifugal forces far exceeding gravity, enabling rapid and efficient solid-liquid separation.
Continuous Screw Discharge
A differential speed is maintained between the screw conveyor and the bowl, continuously discharging solid particles and enabling non-stop discharge.
Adjustable Differential Speed Design
The differential speed can be flexibly adjusted based on material characteristics to achieve the desired solids dryness and liquid clarity.
Dual Motor and Variable Frequency Control
Advanced models are equipped with dual motors and a variable frequency drive, ensuring energy efficiency and stable operation.
Intelligent Control System
A PLC and sensors monitor operating parameters in real time, enabling remote operation and fault alarms.
Wear-Resistant and Corrosion-Resistant Materials
High-strength stainless steel, alloy steel, or tungsten carbide coatings are used for different materials to ensure equipment life.
