Abstract
Procedimiento para el secado y la molienda fina de carbón destinado a la alimentación de los hogares de carbón en polvo de una instalación de calcinación consistente en una etapa de precaldeo, una etapa de calcinación, así como una etapa de sinterización, en especial para la producción de cemento clinker, caracterizado porque para el abastecimiento del proceso de secado con gas de secado de un grado suficiente de insertización y de capacidad térmica, se deriva al menos una corriente parcial del balance de gas de la etapa de precaldeo y/o de la etapa de calcinación, que es conducida por el camino aproximadamente más corto al proceso de secado y molienda.
