ZK SEPARATION Decanters for Sludge Dewatering Processing
ZK sludge centrifuge is professional industrial separation equipment for sludge dehydration treatment. The central part is composed of a cylindrical bowl. When the equipment is working, the bowl rotates at high speed to separate the wastewater liquid from the solid and discharge the liquid and solid substances separately through the discharge port. The equipment has an automatic control system and can work continuously without interruption. Which can significantly improve the efficiency of sludge treatment.

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 of 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 of 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 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.
