Zusammenfassung:The invention relates to a method for producing cement, wherein cement starting material is ground in at least one ball mill and is subsequently separated into fine material and coarse material in a classifier, the coarse material being fed to the ball mill again. Subsequently, the fine material of the classifier is quantitatively divided into a first partial amount and a second partial amount. The first partial amount forms a first cement, while the second partial amount of the fine material is fed to a dry-operated stirred ball mill for further grinding and the resulting second cement is selectively mixed with the first cement or used as a separate product.
