The present invention relates to a rotary-type metering device making it possible to dispense granular substances consisting of fine particles which are difficult to handle. The metering device consists of a spherical core rotating around a horizontal axis inside a casing comprising a feed orifice and an outlet orifice. The spherical core comprises at least one cavity having an opening at the surface of the core, and sides and bottom within the core. This cavity has the shape of a volume consisting of two volumes of revolution, contiguous and coaxial, V1 and V2, with an axis perpendicular to the axis of rotation of the spherical core. The volume V1 is a truncated cone of revolution or a cylinder of revolution. |
