ABSTRACT:
Precision weighing and filling of comminuted materials is carried out at high speeds by advancing the material to be weighed into a rotatable pan, applying an unbalanced electromagnetic force to the pan so as to cause it to rotate through a predetermined angle to dump the contents into a tiltable discharge funnel and selectively locking the pan in a predetermined rotational position in preparation for refilling and the next dumping operation, all in rapid succession.
