    cement (Kihara and Visedo 2014). A rotary kiln in a dry cement production can be divided into five zones (Stadler et al. 2011): heating zone, calcining zone, transition zone, firing zone and cooling zone. The position of the zones along the kiln depends on the temperature and the chemical reactions being performed in the solid (Spang 1972).
