CITICIC Kiln Shell en Luoyang, Henan, China

The rotary kiln shell serves as the main structure of the rotary kiln, typically constructed from steel plates that are pre- fabricated into sections and then either riveted or welded together. Several kiln ring types are mounted on the shell, resting on corresponding support rollers, allowing the material to gradually move from the inlet end toward the discharge end. To ensure proper movement, the rotary kiln shell typically has a slope of 3% to 5%. To protect the kiln shell, a layer of refractory bricks, 100-220 mm thick, is applied to the interior.
The kiln shell is a cylindrical steel structure that forms the main body of a rotary kiln, used in industries such as cement, lime, and chemical processing. It serves as the vessel in which raw materials are heated, dried, and processed through controlled thermal conditions. The kiln shell is a critical component, influencing the efficiency and durability of the kiln.
