Double Shaft Shredder
The SUHUI double shaft shredder is a heavy-duty industrial machine engineered for processing bulky, thick-walled, and mixed plastic waste that single-shaft shredders cannot handle efficiently. Its dual counter-rotating shaft design, equipped with interlocking hardened steel blades, delivers exceptional shredding torque and cutting force for high-volume plastic size reduction.
Product Description
The SUHUI double shaft shredder is a heavy-duty industrial machine engineered for processing bulky, thick-walled, and mixed plastic waste that single-shaft shredders cannot handle efficiently. Its dual counter-rotating shaft design, equipped with interlocking hardened steel blades, delivers exceptional shredding torque and cutting force for high-volume plastic size reduction.
The two shafts work in tandem to shear, tear, and compress materials into uniform, manageable fragments. With an automatic reverse function and hydraulic overload protection, the machine handles challenging materials — including large plastic drums, industrial containers, pipes, profiles, and jumbo bags — with minimal jamming and consistent output.
Widely used in plastic recycling facilities, waste management operations, and manufacturing plants, the SUHUI double shaft shredder is the first-stage size reduction solution for downstream washing lines, granulators, and pelletizing systems.
Key Features of SUHUI Double Shaft Shredder
- Dual Counter-Rotating Shaft System: Interlocking hardened steel blades on two shafts deliver maximum torque and cutting force for tough, thick plastic materials.
- Scissor-Cut Blade Action: Interlocking blade geometry shears and tears materials cleanly, reducing energy consumption and blade wear compared to impact shredding.
- Hydraulic Overload Protection: Automatic hydraulic pressure adjustment prevents jamming and protects the drivetrain when encountering hard or oversized material.
- Auto-Reverse Function: Intelligent control system automatically reverses shaft rotation to clear blockages, minimizing manual intervention and downtime.
- Intelligent PLC Control Panel: Real-time monitoring with touchscreen interface for speed adjustment, output settings, and operational diagnostics.
- Heavy-Duty Reinforced Frame: Thick steel construction provides structural rigidity under continuous high-load operation.
- Modular Blade Configuration: Quick-change blade cassettes reduce maintenance time and allow customization of output fragment size.
- Low Speed, Low Noise Operation: High-torque, low-RPM design minimizes noise and dust emissions for compliant, eco-friendly operation.
- Versatile Feed Opening: Large feed hopper accepts irregularly shaped or oversized plastic pieces without pre-processing.
- Safety Systems: Emergency stop, safety door interlocks, and vibration sensors protect operators during operation.
How the Double Shaft Shredder Works
- Material Loading: Bulk plastic waste — such as drums, containers, pipes, jumbo bags, or film bales — is loaded into the feed hopper via conveyor or forklift.
- Dual-Shaft Engagement: Two counter-rotating shafts pull material inward simultaneously, gripping and drawing it into the cutting zone.
- Shearing & Tearing: Interlocking blades on each shaft shear through the material in a scissor action, breaking it into progressively smaller fragments with each pass.
- Overload Management: If the system detects excessive resistance, it automatically reverses shaft rotation to release the blockage before resuming forward shredding.
- Size Control & Discharge: Shredded fragments exit through the lower discharge opening at the controlled output size, ready for conveying to a granulator or washing line.
