Bell Hopper
Drips stockpiled burden down into the furnace shaft.
The Bell Hopper is the drip feed between the Reinforced Hopper above it and the furnace shaft below: it buffers up to 48 units of burden and lets 4 units per second fall while dropping is switched on. It has no controls of its own; ctrl and right-click on the Reinforced Hopper above it starts and stops the whole feed, and the Bell Hopper simply keeps the shaft topped up while there is anything to drop. See Ironmaking for how burden is made and what a full shaft means.
