ARJES Impaktor 850 vs Vermeer LS3600TX — Single-Shaft Shredder Comparison

Both are heavy single-shaft shredders in a similar weight class — the Vermeer LS3600TX at 32.49 t with a 340 kW CAT C13B, the ARJES Impaktor 850 at 24 t with a 340 kW CAT C9. They are commonly shortlisted together for C&D and green-waste processing where the choice hinges on driveline architecture (mechanical vs asynchronous hydro-mechanical), regulatory transport, and serviceability.

For multi-site CEE deployments, the ARJES Impaktor 850 delivers lower TCO through 35–45 l/h fuel consumption (vs 73.1 l/h peak for Vermeer), 2-hour cassette swaps, and borderline GVW compliance. The Vermeer LS3600TX offsets with faster localized tip replacement (0.5–1 h) and superior belly conveyor serviceability, but its heavy-haul transport costs (€3,000–8,000/move), higher fuel burn, and shock-load bearing fatigue offset these advantages over a 10,000-hour horizon.

The Vermeer ball-detent torque limiter is a mechanical clutch that disengages the driveline when torque exceeds its set point (2,822 Nm), protecting the gearbox from catastrophic failure. However, before disengagement, the full kinetic shock load is transmitted to the rotor, bearings, and tooth tips. The ARJES asynchronous hydro-mechanical drive absorbs shock loads hydraulically throughout the overload event — there is no discrete trip point, so the system compresses the peak impulse rather than passing it. For contaminated C&D with embedded rebar, the ARJES approach yields significantly lower cumulative bearing fatigue.
