Particularly in the cement industry, ball mills have largely been replaced by roller mills for new plants [2], as they are compact, and the installation cost is smaller [3]. The vertical roller mills are up to 40% more energy efficient than ball mills [4]. The milled particles are typically a few microns to 100 μm in size.
The vibration of the rolling mill has been a persistent issue affecting its safe and stable operation. To address the vibration problem in the F2 stand of a continuous rolling mill, this paper establishes a digital twin model of the rolling mill. Based on the digital twin model, a rolling mill virtual commissioning framework has been proposed to …
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 ...
