The single‑shaft shredder can process various bulky industrial wastes such as plastic lumps, thick sheets, thick‑walled pipes, wood, films and tangled materials. Adopting a low‑speed high‑torque single rotor structure and equipped with a hydraulic pusher. After materials are fed into the hopper, the hydraulic ram continuously pushes materials toward the rotor. The rotating moving blades tear and shear materials together with fixed blades. Fragments smaller than the screen aperture are discharged from the bottom, while oversized materials remain in the chamber for further shredding. It mainly reduces volume and cuts large‑size waste into uniform pieces for subsequent conveying, washing and crushing‑granulation, acting as primary coarse‑shredding equipment for solid waste recycling.
