Abstract:
Feed device (100; 100â€²; 300) for loading materials into a shaft furnace (101; 301), from of at least one reservoir (103, 105; 303, 305), with a revolving chute (107, 111; 307, 311) comprising a cylindrical basic body (107; 307) that can be driven so as to rotate about a first, substantially vertically oriented axis of rotation (A1) with a first drive mechanism (119) and a feed chute (111; 311) that is fixedly attached to an outlet (107a) of the basic body and can be rotated therewith, characterized in that the feed chute is composed of an upper part (113; 313), which is adjacent to the outlet of the basic body and extends longitudinally at an angle to the first axis of rotation, and a lower part (115; 315), which is rotatably connected to the upper part and comprises a second drive mechanism (127; 127â€²) for rotation about a second, substantially vertical axis of rotation (A2) spaced apart from the first axis of rotation.
