Abstract
An apparatus for feeding waste tire chips (12) to an incinerator (11) having a feed chute (13) comprises a container (17) provided with a screw feeder (22, 23) at its bottom, upper and lower two vibrating feeders (24A), (24B), and a transfer conveyor (36) extending between the lower vibrating feeder (24B) and the feed chute (13). The screw feeder (22, 23) is controlled by a first controller (34) in response to an output signal from a first photoswitch (33) which is mounted on the upper vibrating feeder (24A) for detecting the quantity of chips delivered from the container (17). The transfer conveyor (36) and the lower vibrating feeder (24B) are controlled by a second controller (42) in accordance with an output signal from a second photoswitch (41) which is mounted on the feed chute (13) for detecting the quantity of chips to be fed to the incinerator (11) at a time. The upper vibrating feeder (24 A) is intermittently operated by a third controller (43).
