Centrifuge for plastics recycling
Enhance your recycling process with a centrifuge designed to efficiently separate and dewater a diverse range of plastics and materials, achieving higher purity and reduced waste in continuous, high-speed operations.

Separates and Dewaters Mixed Plastics Efficiently
The Sorticanter® centrifuge from Flottweg is designed to revolutionize plastic and waste recycling operations. It employs a robust centrifugal method to efficiently separate and dewater mixed plastics, including challenging materials like PVC and fabric fibers. This innovative equipment excels in applications such as plastics recycling, waste processing, and industrial by-product management, producing high-purity end-products like recycled plastic pellets and PVC compounds.
With a continuous, high-speed operation, the Sorticanter® ensures minimal personnel intervention, reducing costs. The machine’s scroll design and high g-forces allow it to handle particles smaller than 1 mm, enhancing separation efficiency and product quality. The integrated system consumes less fresh water and energy, making it a sustainable choice. Constructed for durability, the machine supports process reliability with an average operation time of 8000 hours per year.
Available in corrosion-resistant materials, the Sorticanter® ensures longevity, while its user-friendly interface simplifies operation. Its closed system design minimizes odor exposure, and all components meet stringent quality standards, underscoring Flottweg’s commitment to excellence. Customization options are provided to meet specific processing demands, supported by Flottweg’s engineering expertise and after-sales services.
