Built on Italian core technology and CE Certification, the SOYU Four-shaft Shredder (FS Series) features two-stage differential shearing, low speed & high torque, heavy-duty durability, intelligent safety, easy maintenance and superior adaptability. Specially engineered for shredding bulky, tough and mixed materials, it is widely deployed in industrial recycling and solid waste treatment applications.

Core Advantages

Compliant & Reliable: The entire unit is built on proven Italian technology and holds EU CE Certification. Key electrical components are sourced from world-renowned brands such as Siemens and Schneider, ensuring full compliance with international safety and quality standards.

Two-stage High-efficiency Shredding: The upper and lower four shafts operate at differential speeds, enabling coarse crushing followed by fine shredding. The combined action of tearing, extrusion and shearing delivers higher processing efficiency for bulky, frame-shaped, tough and sticky materials (e.g., plastic drums, refrigerators, IBC totes, tires) with no risk of shaft winding or material clogging.

Heavy-duty & Durable: Main cutters are crafted from DC53/D2 high-alloy wear-resistant steel and auxiliary cutters from die-forged components, all supporting multi-surface regrinding and reuse. Main shafts undergo hardening treatment, and the thickened cutter box is annealed after welding, boasting exceptional resistance to high torque and impact.

Intelligent & Low-consumption: Controlled by a PLC system with a touch screen, supporting automatic start/stop, reverse rotation and overload protection. Driven by planetary reducers, it delivers low speed and high torque, consuming less energy at the same production capacity while ensuring easier compliance with dust and noise emission standards.

Cost-effective Maintenance: Modular design with high part interchangeability; equipped with clamshell bearing housings and hydraulic flip-up maintenance doors for quick cutter replacement and foreign object removal. Screen meshes can be replaced in sections and cutters are repairable and reconditionable, keeping operation and maintenance (O&M) costs well-controlled.

Superior Adaptability: Capable of processing frame-shaped and hollow materials without additional pressing mechanisms; upper cutters deliver self-cleaning performance against lower cutters. Customizable screen mesh apertures range from 50mm to 100mm, perfectly matching diverse recycling processes and requirements.

Core Features

Differential Shearing Structure: Inter-gear transmission between the four shafts creates differential speeds, enabling automatic feeding with anti-winding performance for smooth material intake and uniform shredding particle size.

Dual Overload Protection: Integrates mechanical torque limitation and electrical overload protection. The equipment automatically shuts down or reverses when encountering foreign objects, preventing damage and ensuring maximum operational safety.

Intelligent Operation: The PLC control system supports automatic overload detection, reverse rotation and remote monitoring, allowing stable operation by a single operator.

Enhanced Sealing & Long Service Life: Multi-layer combined sealing provides superior dust, water and contamination resistance. Imported components deliver high load capacity, ensuring continuous and stable equipment operation.

Customization Capability: Customizable cutter claw count, with tailor-made solutions available based on specific material types and production capacity requirements.

Optimized Structure: One-piece cutter box with CNC machining ensures high precision and structural strength. Extended main shafts, externalized bearing housings and built-in material chutes minimize wear on oil-sealed bearings caused by material accumulation.

Typical Applicable Materials

Drums & totes, bulky waste, scrap metal, tires, waste paper, plastics, wood, e-waste, medical waste, paper mill waste, industrial solid waste, municipal solid waste, etc.
