Abstract
The apparatus comprises a distribution spout and a hopper which has two containers mounted thereabove provided with sealing valves and a metering member. In order to simplify the weighing system, the hopper is independent of the mouth of the furnace and is located inside a sealed chamber. The hopper is suspended by a device which enables it to be coupled to the container which is being emptied and to be uncoupled from the container which is being filled.
