tensile fracturetensile fractureTensile fracture: a material failure mode where the shredder shafts pull and tear the feed material apart, dominant at high RPM and low specific loads., cutting regimecutting regimeCutting regime: the operating mode where the shaft blades slice through feed material with a shearing action, preferred for clean fraction output., TCOTCOTotal Cost of Ownership: the comprehensive lifetime cost including purchase price, fuel, wear parts, maintenance, and residual value depreciation., OPEXOPEXOperational Expenditure: recurring costs of running the shredder — fuel or electricity, wear part replacement, scheduled servicing, and operator wages. — wear cassettewear cassetteWear cassette: a modular, replaceable cutting insert set mounted on the shredder shaft. Quick-swap design minimises downtime during maintenance., twin-shafttwin-shaftTwin-shaft design: two counter-rotating shafts equipped with interchangeable cutting cassettes that work in concert to shred industrial waste.
Imported Asian shredders offer a disruptive 30-50% CAPEX discount upfront. However, in the brutal conditions of Balkan CDW recycling, this is a false economy. The true TCO is dictated by machine uptime and part availability. A €50,000 saving is erased by a single 72-hour downtime event waiting for non-standard bearings.
Legacy European and imported systems permanently weld shafts to the bed. Arjes consolidates the entire primary crushing unit (shafts, bearings, frame) into a single 2,000 kg cassette. Using a standard excavator, the entire heart of the machine can be vertically extracted and replaced. Fleet reliability is verified by 1,500+ active units worldwide.
A worn concrete cassette can be extracted and replaced with a standby unit within 4 hours. The machine returns to active crushing the same morning, while the worn unit is transported to a clean workshop for hard-facing. This modularity ensures maximum asset utilization and protects gross margins.
