ABSTRACT:
A self-adjusting powder distributor--which is particularly intended for use with alumina calcination apparatus--comprises a casing with a permeable partition, a plurality of outlets, and means for introducing preheated hydrate above the partition and fluidizing air therebelow. The fluidized hydrate withdraws through outlets of the casing for further treatment or partly as final product. The casing is provided with means by which the amounts and mutual ratios of the withdrawing material can be adjusted according to preselected values by altering the cross-sectional flow area or the level of the outlets.
