PARTICULATE SUPPLY DEVICE AND PARTICULATE MEASURING DEVICE

WIPO Patent Application WO/2008/056514

A1

[PROBLEMS] A particulate supply device capable of supplying a trace amount of particulates and a particulate measuring device. [MEANS OF SOLVING PROBLEMS] A plurality of particulate passing holes (14B) are formed through the bottom wall (14) attached to the small-diameter tube unit (12) of a particulate drum (10) provided to a particulate supply device (100). Since, only when particulates are set at rest in the small-diameter tube unit (12), particulates stick together to form a particulate arch that blocks the particulate passing holes (14B) allowing no particulate to flow out through the holes (14B). When a bottom turning member (26) is turned above the bottom wall (14), the particulate arch crumbles to allow particulates to fall through the holes (14B). When the bottom turning member (26) is stopped turning, a new particulate arch is formed immediately to block the holes (14B). Since only a trace amount of particulates falls when a particulate arch crumbles, a trace amount of particulates can be supplied and measured by controlling the rotation of the bottom turning member (26).
