Weighing scale with rotor disc

The utility model relates to a weighing scale with a rotor disc, the weighing scale with rotor disc can be used for contimuously weighing the dynamic states of solid materials and is improved on the basis of the rotor weighing balance of the original petent. An impeller type or a hopper group type rotor mainly changeed into a rotary rotor disc, a discharge part is changed into a discharge scraper, and the discharge scraper and a central barrel are combined to have the action of a feed port. The improved weighing scale with rotor disc is suitable for weighing solid materials whose particle diameters are less than 600m/m and temperatures are less than 500 DEG C.
