Why Choose ZK Decanter Centrifuge?

Reliable Quality

The bowl (core component) is made of SAF 2205 duplex stainless steel by centrifugal casting process, and its performance is superior to conventional 304 and 316. All weld joints have undergone flaw detection and thermal treatment, and are provided with certificates of conformity or records for traceability.

Stable Operation

The dynamic balance precision of the centrifuge is ≥ Class 2.5, which is superior to the requirement of the standard so that the centrifuge can be operated smoothly and its longevity is extended. The noise of the complete machine is < 85 dB, the vibration intensity is < 7.1 (load) and 4.5 (no-load). It is equipped with a mechanical and electrical dual overload protection device to ensure safe operation.

Long Service Life

The screw conveyor and bowl adopt the most advanced, reliable and convenient wear-resistant treatment technology and structure in China. All bearings adopt original imported NSK/SKF bearings. The electric control box is made of electrical elements from famous brands such as Siemens and Schneider.

High Degree of Automation

ZK decanter differential speed automatic control technology can automatically adjust the screw conveyor’s differential speed, to prevent overload and blockage. The complete machine is equipped with a bearing temperature sensor and vibration sensor, and is provided with alarms for main motor overload, differential over torque, low differential speed, etc. Meanwhile, its supporting frequency conversion (flameproof) control cabinet can realize automatic start and stop with one key.

How Does a Decanter Centrifuge Work?

Decanter centrifuge is mainly composed of a feed tube, a bowl, a screw conveyor, and solid/liquid phase discharged outlets. In the separation process, the raw material is pumped into the bowl (also called a rotating drum) through the feed tube. Then, the bowl and the screw conveyor rotate at a high speed in the same direction at a differential speed. By centrifugal force, the solid particles with higher density are collected and compacted on the wall of the bowl, then be pushed to the outlet of the bowl by the screw conveyor. The clarified liquid leaves through a paring disc (internal centripetal pump). Eventually, the separation of the solid and liquid is achieved.
