Abstract

See full text

A shaft furnace charge material distribution device includes a main housing, a distribution chute, a suspension rotor and an adjustment rotor, which are rotatable about a vertical axis. The chute is suspended to the suspension rotor to rotate therewith for circumferential distribution of charge material and is adjustable in orientation for radial distribution of charge material. A differential gear interconnects the suspension rotor and adjustment rotor and is configured to transmit to the adjustment rotor the same speed of rotation that is imparted to the suspension rotor by a main rotation drive unless an adjustment drive imparts differential rotation to the adjustment rotor. The device includes two gear casings arranged on the main housing and a shaft arrangement. The first gear encloses a gear mechanism connecting the main rotation drive to one output shaft. The second gear casing encloses the differential gear connecting the adjustment drive to another output shaft.
