In the expansion chamber, the airflow separates the material into a stone fraction and cleaned usable fraction, which conveyors remove to opposite sides. Fibrous materials are collected in the container downstream of the suction blower. Using the same principle, stones can be cleaned of undesired biomass.

Separation remains dependable even with varying material properties, by adjusting the feed conveyor speed, blower speed and the separating vertex. Large access doors to the separation chamber and engine compartment plus a swivel-mounted suction blower make maintenance simple and convenient.

The single-axle trailer configuration makes the machine easy to manoeuvre, and it is approved for 80 kph (50 mph) road speeds, so transportation is no problem. The standard version of the machine uses grid power. As an option it can be fitted with a turbo diesel generator The hybrid drive design ensures low energy and maintenance costs.
