AbstractAn apparatus, which is intended for metering bulk materials, has a rotatable cell wheel (9) and a stirrer (2), arranged above the latter, and operates reliably even in the case of very sluggishly flowing bulk materials, in particular with small metering capacities, i.e., with the cell wheel (9) rotating slowly. For this purpose, the invention provides two different, isolated drives for the stirrer (2) and the cell wheel (9).
