Analysis and Modeling of Key Data for Ball Mill Load in Cement Grinding Process

摘要

Ball mill load condition directly relate to the quality of cement products, use the production data to establish an accurate mathematical model is helpful to control the ball mill in a stable state. Aiming at the important parameter of cement combined grinding ball mill load, took the production process as the starting point, analyzed control and controlled variables of mill load, a large number of instruments data were collected through OPC technology, after the moving average filter and correlation analysis calculate, obtained the data that could be used for modeling, the ball mill load forecasting model was established by subspace method, simulation demonstrate the effectiveness of the method.
