PROCESS CONTROL FOR CEMENT GRINDING IN

2017-10-27  The VRM is a type of grinding mill integrated with multi functions such as grinding, drying and separation, used for grinding of coal, petroleum coke and minerals. Most recently this technology has been employed for comminution of Blended, Slag and Port Land cement grinding. The cement grinding and drying system be dovetail of a large array of obsolete incompetent equipment and was completely replaced by a single VRM, it improves the fineness and diminish the maintenance and power consumption [1, 34, 36]. Optimization of cement grinding using standard bond grinding calculations based on population balance models is successfully applied [4, 38]. Various grinding laws, energy relationships, control
