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].

SikaGrind® for vertical roller mills

2021-8-1  The grinding of raw material and especially the challenging slag grinding is since many years almost completely in the hands of VRM.In a ball mill, the particles are ground by repeated impact forces. The material needs usually more than 20 minutes from mill entrance to outlet, uncountable impacts take place on this way. Depending on the eciency of the separator and the Grinding Aid, agglomerates of fine particles are rejected and pass the ball mill again. Repeated impact and attrition cause a certain pro-portion of very fine particles and a broad particle distribution. Expressed as inclination of the particle size distribution according RRSB, cements from ball mills
