Abstract
An apparatus for charging feed material through an opening into a furnace has a fixed structure and a moveable door. The moveable door together with the fixed structure defines the opening. The moveable door is mounted for movement toward and away from the fixed structure to widen and narrow the opening. The moveable door is biased toward the fixed structure. The moveable door and the fixed structure create a V-shaped downwardly pointing channel to direct the feed material being fed through the opening by gravity.
