Single Shaft Shredder’s “Anti-Entanglement” Technology

In the plastic recycling industry, bulk bags (jumbo bags), fishing nets, and stretch film are considered the most difficult “entangling materials” to process. Many recyclers, when evaluating equipment, ask: “My materials are mainly waste agricultural film and reinforced bulk bags; will a single shaft shredder really not get jammed?” Because these materials are extremely tough, when they enter ordinary crushing equipment, they easily wrap tightly around the cutter shaft like ropes, leading to motor overheating and shutdown, or even causing expensive equipment damage.

So, how to achieve efficient sorting and shredding of these flexible materials? The single shaft shredder developed by SUNYGROUP provides the standard answer.

1. The core of the SUNYGROUP single shaft shredder lies in its precision gap control system. We control the cutting gap between the moving and fixed blades within a very small range through technical means. When bulk bags enter, the powerful shearing force will “cleanly and efficiently” shred the material the moment it contacts the rotor, giving it no chance to wrap around. V-shaped layout design: The blades adopt a V-shaped cutting trajectory, which not only reduces cutting resistance but also prevents material accumulation on both sides of the machine casing.

2. Special cutter shaft: High torque output and wear resistance. To cope with the friction and heat generated by high-toughness fibers, our cutter shaft system has been comprehensively upgraded: Wear-resistant coating: The surface of the shaft body is treated with a special process, significantly reducing the friction resistance with soft fibers and reducing material melting and adhesion caused by heat. High-torque drive: Coupled with a heavy-duty hydraulic feeding system, even if the material accumulates thickly, the equipment can overcome the resistance with powerful instantaneous torque, ensuring that the “tangled mess” is smoothly transformed into shredded pieces.

3. Intelligent PLC protection: Preventing machine burnout due to entanglement. Although our design greatly reduces the probability of entanglement, for added safety, the equipment has a built-in intelligent monitoring system: Once an abnormal rotor load is detected, the PLC will issue an automatic reverse command within milliseconds, nipping the entanglement risk in the bud and completely eliminating the need for manual cleaning.
