摘要： A screw having a field replaceable flight. The screw includes a barrel and a helical flighting that is removably attached to the barrel by a plurality of brackets. The helical flighting includes a plurality of segments, each segment includes first and second opposing faces having an opening extending there though and side edges. The segments are positioned side by side to generally cooperatively form the flighting of the screw. At least one face of each segment includes raised bosses. The raised bosses project perpendicularly outwardly from the face of the segment to form a pocket within which the bracket is received. The segments are removably attached to the barrel by inserting a segment forming part of the flighting within the pocket and then removably fastening the segment within the pocket.

摘要： A rotary hearth furnace for treating metal oxide materials comprises a hearth mounted for rotary movement within an enclosure. One or more fuel burners are positioned above the hearth. The burners are operably fired to heat the furnace so that heat radiates toward the hearth. One or more oxygen nozzles are positioned between the hearth and the burners in a manner that avoids substantial contact between the oxygen and the briquettes, thereby creating a quiescent zone immediately above the briquettes, with the quiescent zone being sufficient to minimize reoxidation of the reduced briquettes, and minimize entrainment of particulate matter from the briquettes.

摘要： 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.
