The POLDOS® flow regulating conveyor continuously conveys fine-grained bulk materials such as raw meal or coal dust at a controlled flow rate.

The POLDOS® is used for pneumatic feeding of cyclone preheaters and for dosing coal dust to the burners of the rotary kiln and calciner.

The advantages of the POLDOS® are · high flow-regulation precision · calibration during operation · low-maintenance operation · low energy requirement and · uniform and troublefree metered feeding.
