  • 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 factors and controller design for cement grinding

    2004-11-1 · Due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5–8 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer than Portland, this figure would be even higher.
