Designed for reliability, flexibility, and consistent output size, SSH shredders are ideal for recycling facilities requiring uniform material preparation before granulation or further processing. SMART SHREDDING TECHNOLOGY & ADVANTAGES • Single Rotor – Maximum Control: Customized high-alloy wear-resistant steel blades mounted on a robust single shaft ensure aggressive intake and efficient size reduction across mixed material streams. • Programmable Hydraulic Pusher: An intelligent hydraulic feeding system continuously pushes material toward the rotor, optimizing throughput and preventing idle rotation. • Automatic Anti-Jam System: In case of overload or blockage, the rotor automatically reverses direction. This protects the machine and ensures uninterrupted operation. • Screen-Controlled Output Size: A heavy-duty screen located beneath the rotor determines the final particle size. Material remains inside the chamber until it reaches the required dimensions, ensuring a homogeneous output. • Industrial-Grade Components: Siemens/WEG motors, SKF/FAG bearings, and Schneider or ABB electrical systems ensure durability and long service intervals. Fully CE-certified for international compliance. APPLICATION AREAS • Cable Recycling: Copper and aluminum cables, wiring harnesses. • Plastic Materials: HDPE, PET, film, lumps, injection waste. • Electronic Scrap (WEEE): PCBs, electronic components, mixed e-waste.
