Abstract

Método para fabricar productos de polvo mineral fino utilizando sistemas que consisten en uno o más clasificadores de aire, separadores de polvo como ciclones y/o filtros, por lo menos un ventilador así como los conductos tubulares o canales que conectan estos aparatos para el transporte de aire, caracterizado porque un controlador (1) ajusta la humedad relativa del aire de clasificación en el clasificador de aire, de tal manera que la humedad relativa del aire de clasificación en el clasificador de aire se mantiene en el rango del 15% al 35%, teniendo el producto de polvo minera CaCO3 un tamaño de partícula promedio menor a aproximadamente 5 mm.
