PROBLEM TO BE SOLVED: To provide a device for pelletizing powder capable of stably yielding a pellet product from powder irrespective of its moisture concentration and fluidity. SOLUTION: In the device for pelletizing powder, the first gate member 210 can be displaced, by virtue of a gate displacement mechanism 230, on the outer peripheral face FR of the first roll member 110 in the direction of approaching or distancing itself from the abutment part TP, with the first gate member 210 constituting a part of the feed hopper 200 and communicating with the outer peripheral face FR as far as the vicinity of the abutment part TP from the upper side of the first roll member 110. Thereby the nip angle of the first roll member 110 to which powder is fed on its outer circumferential face FR from a first slope FS of the first gate member 210, can be changed. Thus, powder can stably be pelletized yielding a pellet product irrespective of its moisture concentration and fluidity. COPYRIGHT: (C)2009,JPO&INPIT
