Why the double shaft design dominates
Two counter-rotating shafts with hooked blades grab and tear material instead of cutting it, which handles mixed, bulky and contaminated waste that defeats high-speed crushers. Scrap yards, recyclers and waste handlers choose it as the first stage before sorting, baling or further size reduction.
Key parameters to define
- Material types and the hardest item in your stream.
- Maximum input size and target output piece size.
- Throughput per hour at your duty cycle.
- Blade material and thickness for your abrasion level.
- Drive: electric motor or hydraulic, single or dual drive.
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Chamber width | Model series by feed opening | 400–2000 mm |
| Throughput | By material density and size | 500 kg/h – 10 t/h |
| Blade thickness | Interchangeable blade sets | 20–100 mm |
| Power | Single/dual motor, hydraulic | 15–220 kW |
Ranges are indicative. Throughput varies strongly with material type and feed consistency.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Material test | Video of your actual material shredded at rated load? |
| Blades | Blade steel grade, expected life on your material, re-sharpening vs replace? |
| Protection | What happens on unshreddable objects — reverse, clutch, shear pin? |
| Bearings | Bearing arrangement and protection from dust and impact? |
| Scope | Feed conveyor, discharge conveyor and control cabinet included? |
