    A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln. The method is based on the principle of granular movement in a kiln as described by Saeman (1951) and Scott et al., (2008). It assumes the kiln is operating in the rolling regime, the active layer has zero thickness, and the bed is

    3) is heated in a cement kiln to form lime, a process that emits CO 2 as a byproduct. The resulting lime reacts in the kiln with silica, aluminum, and iron oxides present in the raw material to produce clinker. Clinker, an intermediate product, is mixed with a small amount of gypsum and/or anhydrite to make Portland cement
