PROBLEM TO BE SOLVED: To provide a particulate quantitative feeding device capable of smoothly discharging the total amount of particulate, having all properties, in correspondence to a preset feed amount without slipping and capable of obtaining particulate, having a uniform width, in a constantly stable state during a long time in succession. SOLUTION: A knurl-form particulate transfer zone, suitable for a stable feed of power and grain and prevention of a slip, or the transfer zone in which an uneven surface shape is engraved in a given width through surface treatment, is formed in the outer peripheral surface of a feed roll 12. In a bottom opening part 10a of a hopper 10 orienting to the particulate transfer zone at the upper part of the feed roll, a flat plate-form control gate 16 having a tip edge part positioned in a manner to approach the particulate transfer zone of the feed roll is provided and constituted such that an opening is adjustable by revolving reversely to the rotation direction of the feed roll. Further, the opening is regulated and the number of revolutions of the feed roll is adjusted by a control gate.
