Efficient machine learning model to predict fineness, in a vertical

However, fineness soft sensing studies in vertical roller mills are less common than horizontal ball mills in the literature. The authors Ajaya and Hare have successfully made a benchmark with different nonlinear models to predict Blaine's fineness in vertical cement mills [ 10,11 ].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

Application of perfect mixing model for simulation of vertical roller mills

Vertical roller mills (VRMs) are well-established grinding equipment for various tasks in the coal and cement industry. There are few studies on simulation of VRMs. In this research workThe vertical roller mill is an important crushing and grading screening device widely used in many industries. Its classification efficiency and the pressure difference determine the entire producing capacity and power consumption, respectively, which makes them the two key indicators describing the mill performance.
