Dual-shaft shredder designed for processing end-of-life tires. Features bolted and replaceable blades, automated control and robust construction.
Bolted Blade System
The main differentiator of the D57 is its bolted and replaceable blade system:
- Selective replacement: only worn inserts are replaced, not the entire assembly. The blade body (heat-treated carbon steel) has a long service life.
- High wear-resistance steel inserts: lower inventory required (less cost and storage space)
- Bolt locking sized for high axial loads; eliminates thermal fatigue failure points (unlike welded blades)
- Quick change with standard tools (impact wrenches, torque wrenches), without shaft disassembly
- Predictable wear: monitorable through periodic inspection, enables planned downtime

Technical Architecture
- Hexagonal shafts: higher torsional resistance for the elevated and variable stresses of tire processing
- 04 bearings per shaft: stability and extended service life
- Triple sealing: external labyrinth, internal labyrinth and rubber seal (protection against rubber dust and metal particles)
- Automatic overload reversal: reverses rotation in case of jamming
- Segmented side scrapers: remove adhered material from shafts
