Production of Fe Ni by the rotary kiln-electric furnace
May 01, 1987· The plant was moved to the new site. At the new plant, the conventional sintering-electric furnace process was replaced with a rotary kiln-electric furnace process which is more efficient than the former process and is well suited to large scale production. Initially, two electric furnaces of 14 MVA and related facilities were com- pleted in 1968.

Rotary Kilns FEECO International Inc.
Unlike an unheated coating process, here, a rotary kiln heats the coating material to just below liquefaction point, allowing it to coat the heat resistant core more evenly and more securely. This process is commonly seen in the manufacture of roofing granules, where a mineral such as granite is coated with a colored pigment, producing a
