Rotary Kilns: Processes Defined
The difference between this process and a non-heated coating process is that a rotary kiln heats the coating material to just below its liquefaction point. At this heated state, the material can coat the heat resistant core evenly and, since this is a chemical phase change, more securely than a traditional coating process.

For a process to be efficient, we must get most of the energy into the material and later exhaust the rest. In addition to driving the process, heat transfer is also important for the control of the rotary kiln process. This chapter presents the classical heat transfer modes and their equations as they relate to the rotary kiln environment.

Innov Engineering Pvt. Ltd
Rotary Kiln Process. The material is entered into one side of the kiln and as the rotation occurs, the material slides down through the tube and goes through a certain amount of mixing and stirring. Hot gasses pass through the kiln, and these gases either come from an external furnace or may be generated inside the kiln.
