Asynchronous Shaft Kinematics: 160,000 Nm Torque vs Reinforced Concrete
Landfill fee €25/t, fuel consumption 0.27 l/t, and wear factor 0.85 are locked into the shift model.
Evaluation of asynchronous paddle shafts in reinforced concrete. Telemetry confirms Multi-directional Tensile Torsion superiority over traditional synchronous shearing.
THE CUTTING FALLACY
Traditional synchronous shredders attempt to slice through material. When applied to highly abrasive silicates and reinforced concrete, this destroys the metallurgical integrity of the blades. Arjes subverts this by utilizing an asynchronous drive system with Bonfiglioli planetary gearboxes, running independent shafts between 11 and 35 RPM and sustaining a 160,000 Nm torque capacity.
TENSION FRACTURING
Instead of cutting, the shafts grip the aggregate and subject it to multi-directional tensile forces. Since concrete has high compressive but low tensile strength, it shatters along its internal fault lines. This "crushing" principle preserves the hard-faced tool edges and drastically reduces the kinetic energy required per ton.
CONTAMINANT REJECTION
SCU threshold locked at $P_{spike}=345$ bar. Auto-reverse safety margin: 5%. The Bonfiglioli drive train is calibrated to trigger kinetic reversal before reaching the shear stress limit of the paddle shafts. When unshreddable rebar bridges the chamber, the Shredder Control Unit (SCU) detects the hydraulic spike before exceeding the 160k Nm threshold. The automated reverse sequence instantly ejects the contaminant, allowing the over-belt magnet to isolate clean ferrous material without stalling the primary drive train.
