ABSTRACT:
A device for weighing free-flowing or strewable solid material, in particular granular or powdered material, during throughflow, includes an enclosed housing a rotor which is essentially freely rotatable about an essentially horizontal axis of rotation and has at least two adjacent compartments viewed in the direction of rotation, an inlet in the housing for feeding material to be weighed to one of the compartments of the rotor an outlet in the housing for discharging weighed material from the compartments of the rotor, and retaining devices acting on the rotor. The retaining devices includes a magnetic system which is designed to exert on the rotor a retaining force of a predetermined maximum magnitude acting in the opposite direction to the direction of rotation of the rotor.
