Abstract

La presente invención se refiere a métodos y sistemas ejemplares para fabricar cemento en un molino de rodillos vertical (VRM) usando lecturas de sensores de humedad. Esto permite el ajuste de variables operativas como alimentación de material, agua, auxiliares de molienda, flujo de aire, temperatura y sus combinaciones. Las modalidades ejemplares permiten a los fabricantes predecir y mejorar las propiedades del cemento, como la resistencia y el tiempo de fraguado, controlando y gestionando la humedad del aire en el VRM y/o su sistema de flujo de aire.
