Dual-Single Shaft Shredder

The Dual-Single Shaft Shredder is a specialized recycling solution engineered specifically for processing soft, high-tenacity, and easily entangled materials. Unlike traditional shredders that struggle with flexible waste, this innovative machine combines the aggressive “grabbing” capability of a dual-shaft rotor with the high-speed, precise cutting geometry of a single-shaft shredder.

Introduction to the Dual-Single Shaft Shredder

Powered by a dual-motor and dual-gearbox drive system, the KF-SD series ensures high torque and consistent operation. Ranging from the KF-SD600 (150-200kg/h) to the heavy-duty KF-SD1500 (800-1000kg/h), this equipment is the ideal choice for recyclers looking to process films, bags, and nets efficiently without the need for a hydraulic pusher.

Features of the Dual-Single Shaft Shredder

1.Innovative Dual-Single Rotor Design

The machine utilizes two counter-rotating shafts equipped with a dense arrangement of cutters. This design pulls soft material in automatically (self-feeding) while delivering a scissor-like cut, effectively preventing material from wrapping around the shaft.

2. Premium Electrical Components

Control System: Equipped with a PLC system (Xinling / Mitsubishi) featuring automatic overload protection and auto-reverse functionality.
Electric Parts: Uses trusted brands like Delixi / Siemens to ensure long-term electrical stability.

3. Robust Power System

Features powerful Tongli gearboxes and dual motors (ranging from 22kW×2 to 90kW×2), providing sufficient torque to tear through thick bundles of material.

4. High-Grade Blades

The blades are manufactured from DC53 mold steel. This material offers superior hardness and toughness compared to standard SKD-11, significantly extending blade life when processing abrasive or dirty soft plastics.

5. Easy Maintenance

The modular design allows for easy access to the cutting chamber. The bearing seats are designed externally to prevent dust and water from entering the transmission system.

Application of the Dual-Single Shaft Shredder

إن Dual-Single Shaft Shredder excels at processing “soft and tough” materials that often jam standard crushers. Key applications include:

Plastic Films: PE/PP agricultural films, packaging films, and industrial waste films.
Woven Materials: PP woven bags, Jumbo bags (Ton bags), and cement bags.
Fiber & Textiles: Chemical fiber cloth, textile scraps, and waste clothing.
Ropes & Nets: Nylon ropes, chemical fiber filaments, and discarded fishing nets.

الأسئلة الشائعة

What is the main advantage of a Dual-Single Shaft Shredder compared to a standard Double Shaft Shredder?

Standard double shaft shredders rely on shearing and tearing, which often leads to soft films or nets slipping through or wrapping tightly around the shafts. The Dual-Single Shaft Shredder utilizes a specific cutter design that acts like a high-speed scissor. It grabs the material like a dual shaft but cuts it cleanly like a single shaft, ensuring high throughput without tangling.

What is the durability of the blades?

We use DC53 steel for the rotating knives. This is a high-performance cold-work die steel that offers excellent wear resistance and impact toughness. It is specifically chosen to handle the heat and stress generated by shredding tough fibers and films.

How do I choose the right model?

Model selection depends on your required capacity and material size:

Small scale (150-200 kg/h): Choose the KF-SD600.
Medium scale (350-500 kg/h): The KF-SD1000 or KF-SD1200 are ideal.
Large scale (800-1000+ kg/h): For whole bales or high-volume lines, the KF-SD1500 is recommended.
