Abstract
A particulate material feeding device has a particulate material storage tank for storing particulate materials, a delivery device for continuously delivering the particulate materials stored in the particulate material storage tank, a chute which drops and transfers the particulate materials delivered from the delivery device to drop and feed the particulate materials to a feeding position, a blocking body which intermittently enters a blocking position for blocking at least a part of the particulate passage in a cross-sectional direction in the chute, from a non-blocking position, and a recovery path branched from the chute so as to discharge the particulate materials blocked by the blocking body to the outside of the chute.
