摘要
A worm metering apparatus which includes a metering tube having an end, the end has an annular barrier element, made of sintered metal, that communicates with a negative-pressure source and an overpressure source gas source. A pressure meter is also provided, which measures the negative pressure that prevails in a line to the barrier element. To prevent the barrier element from becoming clogged with bulk material particles, the overpressure gas is conducted to the barrier element during the operation of the worm metering apparatus, in order to detach adhering particles of bulk material.
