WEIMA single-shaft shredders support high-standard, industrial-scale recycling

Two WEIMA W5.14 single-shaft shredders support Spanish WURSI Group to recycle plastic waste in high standard and on industrial scale, of which the company processes around 1,500 tons of polypropylene and polyethylene into regranulate every month.

“We have been very satisfied since we purchased the first machine. We quickly bought the second one and hope to integrate the third one next year,” said Javier Perez, Managing Director of WURSI.

WURSI first processes sorted plastic waste manually and feeds it into the two WEIMA shredders via a conveyor belt. There, the material is shredded to between 30 and 100 millimeters, depending on the screen configuration. The resulting flakes form the basis for a homogeneous melt in the extrusion process.

The WEIMA W5.14 shredder is designed for demanding plastic applications. The V-rotor with a diameter of 500 mm and a length of 1,400 mm ensures uniform shredding even with tough materials.

The Siemens PLC control system with touch panel allows precise adjustment of the operating parameters. The hydraulically opening screen basket and the generous inspection flap significantly reduce downtime during maintenance or screen changes.

WURSI uses interchangeable screen segments to be able to react flexibly to material differences – an advantage with changing polyolefin streams.

WURSI does not regard plastic recycling as an ecological flagship, but as a technically demanding value-added process. The combination of mechanical precision and quality-oriented process control results in a regranulate that meets the requirements of modern plastics processing and thus enables a genuine material cycle.
