Abstract

The invention relates to a distribution metering device (1) for a roller mill, comprising a housing (2) with at least one grinding stock inlet (3), at least one grinding stock outlet (4), a feed roll (5) which is arranged in the housing (2) for metering grinding stock into a grinding gap of the roller mill through the grinding stock outlet (4), said feed roll being rotatable about a feed roll axis (SA), a conveyor shaft (6) which is arranged in the housing (2) for distributing grinding stock along the feed roll (5), said conveyor shaft being rotatable about a conveyor shaft axis (FA), wherein the conveyor shaft axis (FA) is substantially parallel to the feed roll axis (SA), and a first fill state sensor (7) arranged in the housing (2) for ascertaining a first grinding stock fill state of the housing (2). According to the invention, a second fill state sensor (8) arranged in the housing is provided for ascertaining a second grinding stock fill state of the housing (2). The grinding stock inlet (3) and the first fill state sensor (7) are arranged at a first end of the feed roll (5) and the conveyor shaft (6), and the second fill state sensor (8) is arranged at a second end of the feed roll (5) and the conveyor shaft (6).
