A plastics recycling shredder by WEIMA Maschinenbau — the WLK 1000 — features a single-shaft shredder with a hydraulic drive that is suitable for shredding thermoplastics, such as PE, PP, PVC, PS, PU and PET, as well as the most diverse duroplastic and elastomer types, the company says.
Even large-volume hollow bodies, long pipes as well as profiles, solid metal and other production waste can be shredded using the WEIMA WLK 1000.
Shredding is a basic requirement for recycling plastic of any type. The better and more homogeneous the input material has been shredded, the easier it is to then produce high-quality recycled material as part of downstream process steps, such as extrusion.
The WEIMA WLK 1000 shredder with its hydraulic drive produces an output of 22 kW. The company says it allows recyclers to significantly boost the energy efficiency per ton of material. Despite its comparatively low kW output it still demonstrates high torque values that are also available permanently.
Material changes are no longer an issue as the rotor speed can be adapted continuously.
WEIMA says the hydraulically driven shredder also scores excellent marks in combination with cutting mills or extruders. The rotor features precision controls. Consequently, the electric motor need not be switched off, even at rotor speeds of zero. As a result, the stop-and-go automatic mode of downstream production machines can be applied more efficiently, causing less wear on components.
The different WEIMA WLK 1000 shredder equipment specifications guarantee optimum adaptation to any application case, the company says. Options to boost the throughput, such as the V rotor with Supercut die clearance adjustment, produce first rate plastics shredding results. WLK shredders can be filled using a conveying belt, a forklift or even manually.
