Industrial Dual-Shaft Cardboard Shredder – High-Torque Recycling Solution for Paper, Plastic & Packaging Waste

Product Introduction

The SY Series Cardboard Shredding Machine represents the latest advancement in waste reduction technology, engineered by our seasoned R&D professionals to tackle the toughest shredding challenges. This dual-shaft shredder delivers exceptional performance across a broad spectrum of materials – from corrugated cartons and cardboard boxes to waste paper, plastics, sponges, fiberglass, and textile rags.

What sets the SY Series apart is its adaptable blade system. Operators can choose from six blade thickness grades (15mm, 20mm, 40mm, 50mm, 75mm, and 100mm) to achieve precise output particle sizes tailored to specific downstream requirements. For processing lightweight or hollow materials, an auxiliary pressure mechanism is available to force-feed the material, significantly increasing hourly output.

Every model in the SY lineup incorporates a dual-shaft drive system with heavy-duty gear reducers, ensuring stable torque delivery at low rotational speeds (18-25 r/min). This design minimizes wear while maximizing cutting force. The integrated dust extraction and collection system maintains a clean workplace, meeting modern environmental standards without compromising productivity.

Whether you operate a waste sorting facility, a paper recycling plant, or a packaging recovery center, the SY Series offers a scalable, cost-effective shredding solution that adapts to your evolving needs.

Technical Characteristics

  • Multi-Material Processing: Effectively shreds cartons, corrugated boxes, waste paper, plastics, foam, fiberglass, and rags in one machine.

  • Customizable Blade Options: Six thickness grades (15–100mm) allow precise control over final particle dimensions.

  • Pressure-Assist System: Optional forced-feed device boosts capacity when processing hollow or lightweight waste streams.

  • Dual-Shaft Drive: Two main shafts with independent reducers deliver high torque at low speed for efficient, quiet operation.

  • Eco-Friendly Design: Built-in dust capture and collection system ensures compliance with environmental regulations.

FAQ

Q1: Which materials can the SY Series handle?
A1: The SY Series is engineered for a diverse range of feedstocks, including corrugated cardboard, paperboard, office paper waste, plastics (films, bottles, containers), polyurethane foam, fiberglass insulation, and cloth rags. It excels with materials that are fibrous, flexible, or prone to wrapping around conventional shredder shafts.

Q2: How does the blade selection impact the output?
A2: Blade thickness directly determines fragment size. Narrower blades (15mm, 20mm) yield finer particles suitable for pulping or granulation, while wider blades (40mm to 100mm) produce larger chunks for baling, transport, or primary reduction. We offer full customization to match your specific process requirements.

Q3: What does the pressure device do and when is it needed?
A3: The pressure device acts as a mechanical pusher that compresses lightweight, bulky, or hollow materials (such as empty boxes and plastic bottles) against the cutting rotors. This prevents material from bouncing back, ensures steady intake, and can increase throughput by 20-40% in appropriate applications.

Q4: Is the machine environmentally friendly?
A4: Absolutely. The SY Series features an engineered dust collection system that captures airborne particles during operation. This protects worker health, keeps the facility clean, and helps operators comply with local environmental regulations regarding particulate emissions.

Q5: How do I select the right SY model for my operation?
A5: Model selection depends on your throughput targets, feed material characteristics, and desired output size. Our technical team typically evaluates factors such as hourly volume, material density, and downstream equipment compatibility. Contact us with your specific data, and we will recommend the optimal configuration.
