    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.
