Patent ID: 8353660

Claim:
A charging device for distributing bulk material in an enclosure, said device comprising: a stationary housing supporting a rotatable structure, said rotatable structure carrying adjustable distribution means so that rotation of said rotatable structure allows circumferential distribution of bulk material and adjustment of said distribution means allows radial distribution of bulk material; a first drive for rotating said rotatable structure; a second drive for adjusting said distribution means; a first rolling bearing comprising a first stationary race bearing a first rotary race coupled to a first gear ring that cooperates with said first drive for rotating said rotatable structure; a second rolling bearing comprising a second stationary race bearing a second rotary race coupled to a second gear ring that cooperates with said second drive for adjusting said distribution means; further comprising a stationary race unit having an inner side presenting said first stationary race and an outer side presenting said second stationary race such that said first rotary race is arranged radially inward with respect to said second rotary race, said first stationary race is arranged radially inward with respect to said second stationary race and said second rolling bearing axially overlaps said first rolling bearing.
