Abstract

The invention relates to a method and device for continuous dosing of bulk material allowing dosing and conveyance capacity to be improved, especially when there are substantial fluctuations in conveyor air flow. A cellular wheel sluice (4) disposed upstream from the dosing device (8) re-directs part of the bulk material to the container (2) when it moves in an upwards direction. The re-directing cells (7) of the cellular wheel sluice (4) leading towards the container (2) are preferably filled to approximately 30 % to improve tightness with respect to leaking air.
