Predictive Controller Design for a Cement Ball Mill Grinding Process
The process model considered in this study is based on first principles which did not exhibit the process dynamics of the real-time scenario. A hybrid model was developed for controlling the cement ball mill grinding process that ensured the stable operation of the plant by avoiding the plugging phenomenon .

How to improve cement plant process for better cement quality
In the process of cement milling, quality control mainly includes fineness, specific surface area and particle distribution control of cement. In cement grinding process , although the specific surface area needs to be measured every once in a while, it has no close correlation with the cement strength and cannot reflect the distribution of cement particles.
