Good dosing – Tietjen feeders
Dosing of free-flowing bulk materials
This variant stands out due to its compact design and the loading of the mill directly from the above-lying upstream container. The design allows for improved, i.e. double, foreign object protection thanks to a magnetic cascade and wind sifting for non-magnetic contaminants. The DA housing is very compact, the centre distance between input and output is only 45 mm. The unit is pressure shock resistant in accordance with the latest standards, tested in practice and certified.
