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.

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.
