The plastic shredder is equipped with a profiled solid-steel rotor with a diameter of 457–750 mm, operating at a low speed of 52–74 rpm. Concave-ground, aggressive 4-way reversible knives are securely mounted in precision-machined grooves on the rotor using special knife holders. This design allows for a minimized cutting gap between the rotor knives and counter knives, ensuring high material throughput, low energy consumption, and maximum shredding efficiency.
Material feeding is handled by a hydraulically driven ram, which automatically pushes material into the cutting chamber based on load-related control logic. The hydraulic system features high-pressure relief valves and adjustable volumetric flow controls, allowing precise configuration to match different material characteristics.
Extremely robust pedestal bearing housings are mounted externally, completely isolated from the cutting chamber. This design effectively prevents dust and debris from entering the oversized bearings, resulting in extended service life and reduced maintenance requirements.
Power for the plastic bottle shredder is transmitted from the motor through a drive belt to an oversized gearbox mounted on one end of the rotor shaft, ensuring stable torque transmission, smooth operation, and long-term reliability.
To ensure maximum operational safety, a safety interlock switch prevents the shredder from starting when the front access panel is open. In addition, emergency stop buttons are installed on both the machine body and the control panel, providing immediate shutdown in emergency situations.
Product Features
Plastic shredders for recycling are engineered to deliver powerful, high-torque size reduction of bulky waste, turning bottles, films, drums, and mixed scrap into uniform 40–100 mm flakes that are easy to wash, pelletize or sell.
Key features include slow-speed rotors that cut dust and energy use, hardened-steel blades that resist abrasion and can be re-sharpened, programmable screens for precise particle control, and automated feeding with metal detection to protect the cutting chamber.
These machines reduce volume by 75–85 %, cut storage and freight costs, and can process PE, PP, PET, PVC, ABS, PC, nylon and carpet at rates from 100 kg/h to over 5 t/h.
Product Applications
Typical applications of High Efficiency Plastic Shredder machine are preprocessing post-consumer packaging, shredding stretch film or big-bags, downsizing purgings and lumps, reclaiming nylon from carpet, preparing plastic lumber feedstock, and destroying expired goods to recover packaging-supporting circular-economy goals while lowering landfill fees and CO₂ emissions.
