Abstract
A charging device () for distributing bulk material in an enclosure, in particular in a shaft furnace comprises a stationary housing () that supports a rotatable structure () carrying adjustable distribution means (). Distribution of bulk material in circumferential direction is achieved by rotation of the distribution means () together with the rotatable structure (). Distribution of bulk material in radial direction is achieved by adjustment of the distribution means (). For rotating the distribution means, usually about the central axis (A) of the charging device, the device () includes a first rolling bearing () with a first stationary race () that bears a first rotary race (). The first rotary race is coupled to a first gear ring () that cooperates with a first drive () for rotating the rotatable structure and thereby the distribution means. For adjusting the distribution means, the device includes a second rolling bearing () having a second stationary race () that bears a second rotary race (). The second rotary race is coupled to a second gear ring () that cooperates with a second drive () for adjusting the distribution means. According to the invention, the first rotary race () is arranged radially inward with respect to the second rotary race (), the first stationary race () is arranged radially inward with respect to the second stationary race () and the second rolling bearing () axially overlaps the first rolling bearing ().
