10,000-hour TCO comparison: 630,000 EUR fuel delta (Volvo Penta 129 kW vs CAT C15 403 kW), 2.95 m oversize transport vs 2.30 m standard, and asynchronous anti-wrapping logic preventing rebar belt cuts.

|---|---|---|
| C&D waste / reinforced concrete | 80 – 110 t/h | 70 – 100 t/h |
| Waste wood / biomass | 15 – 20 t/h (biomass) | Up to 70 t/h |
| Reinforced concrete with rebar mesh | On-demand shred (anti-wrap T-Blade) | Limited (rebar drops through open table, belt cuts downstream) |

At 1.50 EUR/litre and 10,000 operating hours, the ARJES Impaktor 250 EVO II consumes 18 l/h average (Volvo Penta TAD 581 VE, 129 kW) for a 270,000 EUR fuel bill. The Metso M&J PreShred 4000M consumes 60 l/h average (CAT C15, 403 kW) for a 900,000 EUR fuel bill. The 630,000 EUR delta exceeds the purchase price of the ARJES machine itself.
At 2.30 m width and 14.0 t, the Impaktor 250 EVO II ships on a standard 3-axle hook-lift or lowboy across PL/CZ/SK/HU/RO with zero special permits. The Metso M&J 4000M is 2.95 m wide and 35.0 t — squarely oversize, requiring 3–10 day permit lead times, lowboy trailers, and pilot cars. Per-relocation cost delta: 3–5× in favour of ARJES on small-volume C&D jobs.
The Impaktor 250 EVO II uses asynchronous T-Blade shafts with independent reverse and continuous self-cleaning, preventing thin rebar mesh or wire from winding onto the shaft body. The Metso M&J 4000M open cutting table allows long rebar fragments to drop between knives without cross-cut, then to wrap on synchronous shafts — causing friction overheating of Hardox side plates and belt cuts on the discharge conveyor.
The Metso M&J 4000M ships with 403 kW (CAT C15) and cuts up to 70 t/h on waste wood — substantially above the ARJES Impaktor 250 EVO II at 129 kW / 15–20 t/h biomass. For single-site, high-volume primary reduction of homogeneous wood or bulky industrial waste, the Metso delivers throughput that ARJES matches only with the heavier Impaktor 1000 or 1250 D models.
Both are mobile twin-shaft shredders, but in fundamentally different weight and power classes: the Metso M&J 4000M ships at 35.0 t with a 403 kW CAT C15, while the ARJES Impaktor 250 EVO II is 14.0 t with a 129 kW Volvo Penta. They are commonly shortlisted together for primary C&D reduction where CEE logistics and 10k-hour fuel economics override raw power considerations.
At 1.50 EUR/litre diesel: ARJES Impaktor 250 EVO II consumes 18 l/h average for a 270,000 EUR fuel bill. The Metso M&J 4000M consumes 60 l/h average for a 900,000 EUR fuel bill. The 630,000 EUR delta over 10,000 hours exceeds the purchase price of the ARJES Impaktor 250 EVO II itself.
Yes. The open cutting table design — engineered to prevent clogging on bulky feedstock — allows long rebar fragments to drop between knives without a cross-cut. On the synchronous shafts, thin rebar mesh or wire wraps around the shaft body, causing friction overheating of Hardox side plates and downstream conveyor belt cuts. The ARJES Impaktor 250 EVO II uses asynchronous T-Blade shafts with independent reverse and continuous self-cleaning, eliminating the wrapping failure mode.
