摘要

A device for weighing free-flowing or strewable solid material, in particular granular or powdered material, during throughflow, comprises a rotor (5) which is essentially freely rotatable about an essentially horizontal axis of rotation (4; 41) and has at least two adjacent compartments (10; 44, 45) viewed in the direction of rotation, means (2; 46) for feeding material to be weighed to one of the compartments (10; 44, 45) of the rotor (5), means (3; 47, 48) for discharging weighed material from the compartments (10; 44, 45) of the rotor (5), and retaining means (20, 21) acting on the rotor (5). The retaining means comprise a magnetic system (20, 21) which is designed to exert on the rotor (5) a retaining force of a predetermined maximum magnitude acting in the opposite direction to the direction of rotation (18) of the rotor (5).
