FAILURE ANALYSIS OF ROTARY KILN’S TERTIARY AIR
2020-4-6 · Rotary kilns are continuous process equipment used on calcining of nickel ore. The chemical and physical reactions are created by means of heat up the material to predetermined temperatures. Tertiary air fans are attached to the kiln shell to maintain oxidizing/reduction conditions. Special ducts orientate the air flow inside the kiln. In the
