Twin-Shaft Shear System

The High-Torque Cutting Solution for Refuse-Derived Fuel

Twin-shaft shear shredders provide the extreme mechanical advantage required for processing diverse RDF materials into consistent fuel fractions. These robust systems combine intermeshing cutters with massive torque capacity to handle challenging waste streams while maintaining precise output sizing.

Engineered for Maximum Shredding Performance

The system features dual 400-800mm diameter shafts with staggered cutting discs manufactured from forged alloy steel. Hard-faced cutting edges withstand abrasive RDF components while maintaining sharpness through extended service intervals. The gear-driven design delivers synchronized shaft rotation with up to 200,000 Nm of combined torque capacity for processing dense material clusters.

Advanced Cutting Technology

Interlocking cutting discs create a scissor-like shearing action that efficiently processes both fibrous and brittle materials. The precisely controlled cutter clearance (typically 0.5-1.5mm) ensures clean size reduction without excessive fines generation. Hydraulic adjustable anvils allow output size modification during operation to accommodate varying RDF specifications.

Operational Advantages

The counter-rotating shafts (15-30 RPM) generate tremendous cutting force while minimizing energy consumption. Automatic reverse cycling clears jams without operator intervention. The open rotor design prevents material wrapping while allowing easy access for maintenance. Integrated overload protection safeguards components during unexpected contaminant encounters.

Maintenance for Continuous Operation

Weekly inspection of cutting edges identifies wear patterns requiring rotation. Monthly measurement of shaft alignment prevents premature bearing failure. Quarterly gearbox oil analysis detects potential issues early. Annual recalibration of hydraulic systems maintains precise cutter positioning. Modern systems feature automated wear compensation that adjusts cutter position as components degrade.

Application-Specific Features

Specialized configurations include: heated chambers for wet materials, hardened tool steel cutters for abrasive streams, and explosion-proof designs for volatile fractions. The latest innovations incorporate smart torque monitoring that automatically optimizes feed rates based on material density.
