Impeller packers are specifically developed to fill very fine powdery products (<3 mm) at high speed into valve bags. The filling good is transported into the bag through a turbine which ensures the product flows faster into the bag. Thanks to the reduced air volume the bags used need a lower de-aeration capacity.

Impeller packers are highly suitable for cement and building materials such as lime and gypsum as well as for various chemical products.

For optimal filling the impeller packer is equipped with a sensitive weighing device: NATRO-ATO. This electronic microprocessor-based weighing and control unit is used for gravimetric batching. It comes with a 40 MHz 16 bit microprocessor and a 200 kHz 16 bit analogue / digital converter with highest accuracy.
