Abstract (en)
[origin: US4307987A] The profile of material deposited on the hearth of a pressurized furnace is controlled by means of a charging installation including a lower charging bell which has, suspended therefrom, a variable geometry distributor which may be controlled to select the point of deposition of material delivered to the furnace. The charging bell cooperates with an intermediate storage hopper, positioned within a hermetically sealable casing, whereby the hopper may be alternately filled with material and emptied by permitting the material to fall onto the distributor via an annular opening defined when the bell is lowered.
