Abstract In the combined grinding process of cement production, precise regulation of the stable flow bin weight is crucial for optimizing the pre-grinding process of the roller press and reducing energy consumption in the grinding system. This paper introduces the process flow of the cement combined grinding system and highlights the key role of the stable flow bin in the roller press. Taking the stable flow bin weight as the controlled variable, feeding amount as the controlling variable, and returned powder amount as the disturbance, an active disturbance rejection intelligent control system for the stable flow bin weight is established. Based on the ARMAX model of the stable flow bin weight, an auto disturbance rejection intelligent controller is designed. Experimental simulations demonstrate that the controller can effectively track the setpoint of the stable flow bin weight, with smooth transitions during weight regulation, strong disturbance rejection capability, and no overshoot, showing broad adaptability. This opens up a new path for the precise control of the stable flow bin weight.
