Side-by-side comparison of the ARJES Impaktor 1250 E and Lindner Komet 2800 electric twin-shaft shredders — 500 kW vs 250 kW, cutting torque, throughput on waste wood and RDF, and shaft-change economics.
| Параметр | ARJES Impaktor 1250 E | Lindner Komet 2800 |
|---|---|---|
| Drive concept | Dual-shaft asynchronous low-speed hydrostatic (electric prime mover) | Dual-shaft low-speed direct-electric |
| Prime mover | Asynchronous 2-pole 2 × 250 kW electric motors | Single asynchronous 250 kW electric motor |
| Drive power (kW) | 500 | 250 |
| Drive power (HP equivalent) | 680 | 340 |
| Operating weight (kg) | 46 000 | 18 000 |
| Cutting torque (Nm) | 320 000 | 160 000 (published peak) |
| Shaft speed (rpm) | 15–45 (variable via inverter) | 28–60 (fixed direct-drive) |
| Drive service interval (hrs) | 500 | 500 |
| Shaft cassette swap time (hrs) | 2 (quick-change cassette) | 16 (rotor removal + bearing pull) |
| Setup time (hrs) | 0.5 (SCU auto-calibration) | 4+ (foundation anchor + inverter commissioning) |
| Матеріал | ARJES Impaktor 1250 E | Lindner Komet 2800 |
|---|---|---|
| Waste wood (A1–A3) | 100 – 150 t/h | 60 – 90 t/h |
| Biomass / green cuttings | 150 – 200 t/h | 70 – 110 t/h |
| Commercial / construction waste | 180 – 200 t/h | 40 – 60 t/h |
| Car bodies / mixed scrap | 25 – 30 t/h | Not recommended (wood-optimised geometry) |
| Concrete / asphalt rubble | 140 – 160 t/h | Not compatible |
The Impaktor 1250 E ships with 500 kW of installed electric power (2 × 250 kW asynchronous motors) and 320 000 Nm of cutting torque — exactly double the Lindner Komet 2800’s 250 kW / 160 000 Nm. On high-volume RDF and waste-wood lines, this doubles effective throughput per shaft revolution and halves stall-recovery cycles.
The Impaktor 1250 E is rated for waste wood, biomass, commercial waste, car bodies, and concrete/asphalt rubble from a single platform via shaft cassette changes. The Lindner Komet 2800 is engineered for waste wood and RDF only — running mixed scrap or mineral rubble risks shaft journal damage and warranty voidance.
ARJES quick-change cassette completes a shaft swap in ~2 hours, enabling same-day feedstock changes (e.g. wood → scrap → C&D). The Lindner Komet 2800 requires ~16 hours of in-frame work including rotor removal and bearing pull — a 8× difference that effectively locks the Komet into a single feedstock per campaign.
The Impaktor 1250 E arrives with SCU auto-calibration that brings the machine to production in under an hour after power connection. The Lindner Komet 2800 requires 4+ hours of inverter tuning, VFD parameter matching, and foundation anchor verification before first start — plus civil-works CAPEX for the stationary foundation.
For operators running 100% waste wood or RDF feedstock at moderate volume (60–90 t/h), the Lindner Komet 2800 offers lower CAPEX and a 28-tonne lighter install. ARJES compensates with 2× throughput, 5× feedstock flexibility, and 8× faster shaft changes — decisive for multi-feedstock recycling yards.
Both are stationary electric twin-shaft shredders, but in different power classes: the Impaktor 1250 E delivers 500 kW / 320 000 Nm (2 × 250 kW motors), the Lindner Komet 2800 ships at 250 kW / 160 000 Nm. They are commonly shortlisted together for waste-wood and RDF lines where future feedstock diversification is a consideration.
For pure waste-wood lines, the Lindner Komet 2800 has lower CAPEX and a 28-tonne lighter install. For multi-feedstock yards handling wood, biomass, scrap, and C&D, the ARJES Impaktor 1250 E delivers 30–50% lower TCO through 2× throughput, 8× faster shaft changes, and elimination of secondary dedicated lines for non-wood feedstock.
No. The Lindner Komet 2800 uses wood-optimised shaft geometry and journal bearings that are not rated for ferrous scrap or car bodies. The ARJES Impaktor 1250 E handles car bodies (25–30 t/h), mixed scrap, biomass, waste wood, and concrete/asphalt rubble from a single platform via quick-change shaft cassettes.
