Industrial Double Shaft Shredder
Transform bulky, difficult-to-process waste into uniform, manageable material. Our industrial shredders are the cornerstone of high-volume recycling, engineered for maximum throughput and reliability with minimal downtime.
- High-torque, low-speed design
- Shreds plastics, tires, e-waste & more
- Robust and durable construction
Working Principle: High Torque, Low Speed
The Double Shaft Shredder operates on a simple yet powerful principle. Two hexagonal shafts, mounted with heavy-duty hooked shear blades, rotate slowly into each other. This high-torque motion grabs and pulls material into the cutting chamber, shearing it between the blades. This robust, low-speed design allows the shredder to:
- Quietly and effectively process large, tough, or high-volume feedstock.
- Produce consistently sized output pieces (typically 25-125mm).
- Generate minimal dust and noise for a safer working environment.
Core Advantages
Engineered for maximum uptime, safety, and operational flexibility.
High-Torque Power
Delivers immense cutting force at low speeds to shred tough, bulky materials without jamming.
Durable Alloy Blades
Hardened alloy steel blades are wear-resistant and can be re-sharpened, ensuring long life and low running costs.
Overload Protection
An automatic reverse function protects the drive system from damage when encountering non-shreddable objects.
Low Noise & Dust
The low-speed operation significantly reduces noise levels and dust generation, creating a safer work environment.
Versatile Applications & Materials
Our shredders are trusted across numerous industries for their power and reliability. Key applications include:
Plastic & Rubber Recycling
Effortlessly processes plastic bales, purgings, car bumpers, and tires into uniform strips for further granulation.
E-Waste & Data Destruction
Securely destroy hard drives, circuit boards, and other electronic components, ensuring data security and material recovery.
Metal Scrap Reduction
Ideal for shredding light metal scrap, including aluminum profiles, UBCs (Used Beverage Cans), and sheet metal offcuts.
Industrial & Bulky Waste
Reduces the volume of bulky items like furniture, mattresses, textiles, and industrial drums for easier disposal or recycling.
Wood & Biomass
Processes scrap wood, pallets, and green waste into chips suitable for biomass fuel or secondary processing.
Secure Document Shredding
Provides high-volume, reliable destruction of paper, cardboard, and sensitive documents for commercial shredding services.

Why Choose Our Shredder?
A clear comparison against traditional high-speed granulators for primary size reduction.
| Feature | Rumtoo Double-Shaft Shredder | Traditional High-Speed Granulator |
|---|---|---|
| Best Use Case | Primary shredding of bulky, tough materials | Secondary size reduction of pre-shredded material |
| Input Material Size | Large, unsorted items (bales, tires, drums) | Requires smaller, more uniform pieces |
| Operating Principle | High-torque, low-speed shearing action | High-speed impact cutting |
| Dust & Noise Level | Low dust and noise generation | Higher dust and noise levels |
Frequently Asked Questions
What is the typical output particle size?
The output size depends on the blade width. Our double-shaft shredders typically produce rough strips between 25mm and 125mm wide. For a smaller, more uniform particle size, the shredder is often used as a primary step before a secondary granulator.
Can this shredder handle metal contamination?
While it can shred soft metals like aluminum, it is primarily designed for materials like plastic, wood, and e-waste. The automatic reverse system helps protect against damage from occasional, small, hard contaminants, but frequent processing of heavy metal is not recommended.
What is the maintenance schedule for the blades?
Blade maintenance depends on the material being processed. We recommend weekly visual inspections. The blades are made from high-wear-resistant alloy steel and can be rotated and re-sharpened multiple times before needing replacement, ensuring low operational costs.
