摘要

The present invention relates to a dispensing and metering device (1) for a roller mill, comprising: a housing (2) having at least one grinding material inlet (3) and at least one grinding material outlet (4); ), a feed roller 5 for metering the grinding material through the grinding material outlet 4 into the milling gap of the roller mill, said feed roller being rotated about a feed roller axis SA can - a conveying shaft 6 , arranged in the housing 2 and for dispensing the grinding material along the feeding rollers 5 , said conveying shaft being able to rotate about a conveying shaft axis FA, the conveying The shaft axis FA is arranged substantially parallel to the feed roller axis SA - and a first filling level sensor arranged in the housing 2 , for determining the first grinding material filling level of the housing 2 . (7) is included. According to the invention, a second filling level sensor (8) is provided, arranged in the housing, for determining the second grinding material filling level of the housing (2). The grinding material inlet 3 and the first filling level sensor 7 are arranged at the first end of the feeding roller 5 and the conveying shaft 6 , the second filling level sensor 8 being the feeding roller 5 and It is arranged at the second end of the conveying shaft 6 .
