The refractory lined rotary kiln performs the induration and creates a mixing of the material bed and complete mineral bridging of the green balls into heat hardened pellets. The kiln also gives a robust firing chamber for combustion of fuel. The rotary kiln is a downwards sloping cylinder from the traveling grate to the annular cooler. The

You also calculated the heat losses from the kiln by radiation and convection. All what you need to do now is to sum up all the inputs and all the outputs to calculate the thermal efficiency: Thermal efficiency = (sum of energy outputs) / (sum of all energy inputs. Hope this helps answer your question.

Fundamentally, rotary kilns are heat exchangers in which energy from a hot gas phase is extracted by the bed material. During its passage along the kiln, the bed material will undergo various heat exchange processes, a typical sequence for long kilns being drying, heating, and chemical reactions that cover a broad range of temperatures.
