Abstract

Funnel-type hopper 3 is adapted to positively feed a particulate material, such as a molding powder having a bulk factor of from 2 to 4, through an outlet in the bottom of member 5. Positive discharge is effected by a constantly rotating cutter bar 10. The latter is driven by motor 1 through reduction gearing 9. Motor 1, gearing 9 and bar 10 are supported by lid member 7 having an opening 8 for hopper input. Aperture slide 6 is provided in 5 for on-off feed control. The movement of 10 imparts a constant tumbling action to the material in the lower portion of the hopper. Such action prevents bridging and other causes of clogging which tend to occur near the discharge outlet. The lower tip of bar 10 extends into the outlet as far as possible without interfering with the operation of slide 6.
