· Introduction. The rotary kiln is used in many solid processes, including drying, incineration, heating, cooling, humidification, calcination and reduction. This widespread application can be attributed to factors such as the ability to handle varied loads, with large variations in particle size [1]. The rotary kiln is a slightly inclined steel
