The process of pelletizing iron ore on disc pelletizers is mathematically modeled. Different methods of regression analysis are used to describe the pelletizing operation, and the equations that are obtained are compared with one another. The objective function is optimized based on the yield of green pellets of the class (–14+5) mm.
