ZK SEPARATION Decanters for Plastic Recycling Process
ZK horizontal screw centrifuge is mainly used in the separation process of plastic recycling. The mixed plastic is usually pressed into bundles at the recycling plant and then processed into tiny particles. It is then fed into a mixing tank, mixed with water, and pumped into a centrifuge. The high-speed rotation of the centrifuge generates strong centrifugal force. All particles with a density greater than the liquid are pushed radially outward to the centrifuge drum, while the lighter components float inward and upward. Finally, realize the separation and recycling of plastic particles. ZK decanter centrifuges can be used for plastic recycling in the following industries, including separation of mixed plastic and foil, plastic fiber recycling, PET flake processing, medical plastic particles, carpet fibers, production waste particles, etc.
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.
