Introduction. Vertical roller mill (VRM) is a type of heavy-duty and energy-intensive grinding equipment for many industries, such as cement, steel and chemical industries. It is used to grind slag, nonmetallic ore and other block and granular raw materials into required powder materials. The fine powders can be used as raw materials The two-time breakages are far closer to the actual product size distribution. 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.A cement Vertical Roller Mill modeling based on the

VRM has been a more compact unit is quite smaller about the ball mills thus significantly reducing civil engineering cost about a ball mill plant. Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues. TheIt can also form a combined crushing with a ball mill. The present research is aimed at overflow VRM. For the VRM, scholars mainly consider the research of powder separation performance (Bhasker, 2002, Vuthaluru et al., 2005, Dou et al., 2011) and its application in crushing metal ore (Altun et al., 2015, Li et al., 2020, Boehm et al., 2015Analysis of vertical roller mill performance with
