Combined separation device of rotary drum cooler and stationary magnetic separator

摘要

A combined cooling device and magnetic separator for cooling a heated product stream and removing a magnetic material from the product stream is useful in the production of direct reduced iron (DRI). The combined cooling device and magnetic cooling device and magnetic separators includes a rotating, inclined separating drum (32) that receives the heated product stream at a temperature above the Curie temperature for the magnetic material contained within the product stream. A coolant distribution system (28) cools the product stream to a temperature below the Curie temperature for the magnetic material. A magnetic yoke (58) extends around a portion of the rotating separating drum and removes the magnetic material from the product stream. The magnetic material is collected in a collecting device (66) that directs the magnetic material away from the non-magnetic material contained in the product stream.
