PARTICULATE MATERIAL FEED-OUT DEVICE, PARTICULATE MATERIAL DISCHARGE APPARATUS EQUIPPED THEREWITH, AND PARTICULATE MATERIAL DISCHARGING METHOD

PROBLEM TO BE SOLVED: To provide an apparatus capable of stably feeding a particulate material out of a container with high accuracy without leaving the same in the container at all and capable of feeding out and discharging the particulate material without using a special container requiring a lower discharge port. SOLUTION: A particulate material feed-out apparatus is equipped with the frame provided on a stand in a reversible manner, the container feed-in-and- out device 10 provided on the frame so as to be capable of feeding in and out a container 9, the funnel-shaped discharge hood 13 arranged above the upper opening part of the fed-in container 9 and provided in the frame opening and closing the upper opening part of the container 9 in a liftable manner and the on-off gate 16 for opening and closing the discharge port 15 provided in the liftable hood. A discharge apparatus is equipped with the metering hopper 18 arranged under the discharge port 15 and receiving the particulate material discharged from the container 9 and a control device 23 for controlling the opening degree of the on-off gate 16 on the basis of the detection signal of a metering sensor 19 metering the received particulate material.
