Abstract
La presente invención se refiere a procedimiento para preparar polvos de libre fluidez de agregados granulados de dióxido de titanio no pigmentante, caracterizado porque comprende: - proporcionar preformas sólidas de partículas floculadas de dióxido de titanio pigmentante; - secar dicha preformas sólidas para reducir el contenido en agua libre de las mismas; y - someter dichas preformas sólidas secas a trituración para lograr la reducción de tamaño de dichas preformas sólidas y obtener así dichos polvos de libre fluidez de agregados granulados de dióxido de titanio no pigmentante, cuyos polvos de libre fluidez tienen densidades aparentes comprendidas entre 0.5 y 3.5 g/cm3 aproximadamemnte y en donde una porción substancial de los agregados granulados no pigmentantes que constituyen dichos polvos de libre fluidez tienen un tamaño que oscila desde un tamaño de partícula límite mínimo de 150 micras aproximadamente a un tamaño de partícula límite máximo de 1700 micras aproximadamente.
