A batch material feeder for an electrically heated open-top refractory furnace, particularly a circular furnace, wherein the feeder includes a trough holding batch material and mounted over the furnace top, there being a rotatable agitator within the trough for moving batch material over discharge openings in the trough bottom, so as to deposit the batch material over the top of the molten mass in a manner that provides for a thin uniform layer of batch while assuring proper control of the thickness of the deposited layer. |
