Abstract. This study investigated a mathematical model for an industrial-scale vertical roller mill (VRM) at the Ilam Cement Plant in Iran. The model was calibrated using the initial survey's data, and the breakage rates of clinker were then back-calculated. The modeling and validation results demonstrated that according to the bed-breakage ...
