In the metal recycling industry, the efficient processing of carbon steel scrap has always been a key focus for enterprises. Carbon steel is widely used in construction, automotive, machinery manufacturing, and other fields. The recycling and reuse of its scrap not only brings significant economic value but also plays an important role in resource circulation. The twin-shaft shredder, with its unique design and excellent performance, has become one of the core pieces of equipment for carbon steel scrap pre-processing.
Why do so many carbon steel recycling projects ultimately choose a twin-shaft shredder?
Because what carbon steel scrap fears most is not "hardness," but irregular shapes.
For example:
- Coils of steel strip
- Wound wire
- Structural parts with frames
- Hollow steel containers
These materials cause significant impact on the equipment.
The biggest advantages of a twin-shaft design are:
- Interlocking counter-rotating shafts
- Automatic material pulling
- Anti-wrapping capability
- Low-speed, high-torque continuous operation
- Maintains high stability even with highly fluctuating feed
For a continuous production line, this is more important than simply achieving high output.
Selection Recommendations
When choosing a twin-shaft shredder for carbon steel scrap, we recommend focusing on the following parameters:
| Parameter | Recommended Range | Explanation |
|---|---|---|
| Shaft diameter | ≥300 mm | Large diameter provides greater inertia and crushing force |
| Cutter thickness | 40-80 mm | Thicker blades are better suited for high-strength carbon steel |
| Shaft speed | 15-30 rpm | Low speed reduces impact wear on cutters |
| Drive power | 75-315 kW | Select based on throughput; 30% margin is recommended |
| Cutter material | H13 / Cr12MoV / D2 | High-alloy tool steel, suitable for hardfacing repair |
Typical model reference (based on 1500 mm rotor length):
- Throughput: 5-15 tons/hour (depending on material thickness)
- Output size: 80-200 mm
2 Axis Shredder for Processing Steel Strip Coils
With its powerful shearing capability and excellent adaptability, the twin-shaft shredder has become the preferred equipment for carbon steel scrap recycling pre-processing. Compared to traditional processing methods, it not only significantly improves processing efficiency but also reduces labor costs and energy consumption. For companies engaged in metal recycling, scrap steel processing, or automobile dismantling, choosing a properly configured twin-shaft shredder is an important step toward increasing production capacity and competitiveness.
