TABLE FEEDER

WIPO Patent Application WO/2010/001571

A1

Disclosed is a table feeder that affords a reduction of the pressure exerted on the bottom plate, has a smaller drive means, prevents a particulate material hardening phenomenon, facilitates collection of the particulate material in the discharge portion, and affords improved discharge efficiency. A table feeder (1) comprises: a bottom portion (3) of a particulate material processing vessel (2); a discharge portion (4) which is formed in the bottom portion (3) and has particulate material (P) housed in the particulate material processing vessel (2) discharged therethrough; a bottom plate (5) provided in the bottom portion (3);  a rotating shaft (6) mounted perpendicular to the main face (5a) of the bottom plate (5) in such a way as to rotate at the center of the bottom plate (5); a rotary vane (7) which is rotated by the rotating shaft (6) on the bottom plate (5) and which causes the particulate material (P) housed in the particulate material processing vessel (2) to be discharged through the discharge portion (4); and a drive device (8) for rotationally driving the rotary vane (7). A cone (10) of smaller diameter than the rotary vane (7) is disposed coaxially with the rotary vane (7) in a space above the rotary vane (7) in such a way that the cone (10) covers the center portion of the rotary vane (7).
