Abstract

A silo for storing alumina having a conical outlet at the bottom thereof is fitted with an exchangeable feeding unit mounted over the conical outlet opening. The feeding unit is adapted to close off the outlet opening when in the non-operative position. The feeding unit can take various forms and includes at least one injection nozzle for fluidizing the particulate material.
