Modeling for the Calcination Process of Industry Rotary

Figure 1 Schematic diagram of the rotary kiln. The material going through the kiln is lithopone, an inorganic compound, used as a white pigment. It is first fed into the elevated cold end, the right side of the drying part, and as the kiln rotates it moves along the declining inner bed due to gravity, towards the exit which is at the left side of calciner.
