Abstract	Bentonite is a key raw material in the production of Iron Ore Pellet making [1], where it is used as a binder. It is typically available in the form of solid lumpy mass. To utilize Bentonite in iron ore pellet production, it must be ground to fine powder. At Rungta Mines Ltd. Dhenkanal Steel Plant (RML-DSP), this grinding process is carried out using a Vertical Roller Mill (VRM) also called as a Raymond Mill. To enhance grinding efficiency, ensure size consistency and elimination of manual intervention, we have developed a robust and simple automation process using a Distributed Control System (DCS) to enable autonomous mill operation.
Keywords	Bentonite Grinding, Vertical Roller Mill (VRM), Raymond Mill, Iron Ore Pelletization, Agglomeration, Automation, Distributed Control System (DCS).
