Abstract: Method for grinding a solid in a vertical roller mill (VRM) and a cement composition prepared by the disclosed methods. A method comprises grinding a solid comprising a cement clinker under a water spray in the presence of a grinding stabilizing additive, wherein the grinding stabilizing additive comprises: (i) an alkanol amino acid compound or a disodium or dipotassium salt thereof having the structural formula: (I), (ii) a glycol; or a mixture of (i) and (ii), wherein the water spray level is reduced by at least 5% compared to a control. Cement compositions prepared by the disclosed methods have the pre-hydration level (W k ) equal to or less than 1.5%. The values and preferred values of R 1-3 are disclosed herein.

Abstract: Disclosed are exemplary method and system for manufacturing cement in a vertical roller mill (VRM) using humidity sensor readings. This enables adjustment of operational variables such as material feed, water, grinding additives, air flow, temperature, and their combinations. Exemplary embodiments allow manufacturers to predict and to improve cement properties, such as strength and setting time, by monitoring and managing humidity of air in the VRM and/or its air flow system.
