ABSTRACT:
A device for metering bulk materials with a vertical axis having a rotor featuring radially extending paddles about the vertical axis, and a cover plate, constructed to prevent especially coarse particle materials from being scraped or squashed between the rotor and the cover plate. For this purpose a ring segment type opening is provided in the cover plate, and a recess is provided in the under surface of the cover adjacent the opening to provide a space for producing material slopes underneath, whereby the limiting edge between the inlet opening of the cover plate and the rotor paddles forms an acute angle.
