Plastic extrusion and injection‑molding operations continuously generate large, dense plastic purge lumps (machine‑head lumps). These bulky, irregular hard‑plastic scraps cannot go directly into granulators or extruders. Many factories either pay high waste‑disposal fees or suffer frequent jams, motor overload and premature blade failure when trying to feed whole lumps into standard recycling machines. Valuable polymer material ends up wasted instead of returning to production lines. That is why more extrusion plants and independent plastic recyclers select Huatao’s robust single shaft shredder as their primary pretreatment solution.
Huatao Group carries more than 15 years of manufacturing experience for industrial shredding equipment. Our 600‑1200 series single shaft shredder features heavy thickened steel frames. All critical rotor and blade‑seat components go through large‑scale gantry CNC precision machining, ensuring tight cutting gaps and consistent shear force. Core welding jobs are finished by welders with over 20 years of hands‑on experience, delivering crack‑free welded joints that resist heavy impact from dense plastic lumps during non‑stop shiftswasterecyc....
Equipped with high‑hardness alloy steel moving and fixed knives, the machine breaks solid plastic purge lumps reliably. Interchangeable screen meshes control output particle size within 2‑6 cm. The PLC control system includes automatic reverse rotation and overload protection to prevent component damage when processing unpredictable hard lumps. Customers can customize rotor torque, hydraulic thrust and screen apertures to match their lump size and target hourly throughput.
For plastic‑product factories with in‑house extruders, this single shaft shredder lets you recycle your own purge scrap on‑site and cut raw‑material purchasing costs. For professional plastic‑recycling plants, it delivers uniform feedstock for washing lines and granulation systems, stabilizing final recycled‑pellet quality. Instead of stock‑piling bulky purge lumps or paying third‑party disposal costs, you can turn this hard waste back into revenue‑generating feedstock.
If you are struggling with large‑volume plastic head scrap at your extrusion or recycling plant, reach out to Huatao for customized layout proposals and factory‑direct quotations.
