Abstract

The disclosure relates to a metering apparatus for free-flowing material and to a method for operating such a metering apparatus. The metering apparatus has a metering duct having a closed cross section and further has a rotary drive (M). The metering duct is wound in the form of a screw with a vertical longitudinal axis. The free-flowing material is fed to the metering duct. The metering duct is set via the rotary drive (M) in an oscillating rotary motion about its longitudinal axis with individual rotary strokes, wherein, with each rotary stroke, a partial quantity of the free-flowing material falls out of a lower discharge opening of the metering duct.
