Method and system for grinding fragmentary starting material

The method according to the invention for grinding fragmentary starting material, in particular ores, by means of a dry-grinding system is characterized by the following steps: determining the moisture of starting material over a certain time period, providing at least one screening stage, the cut point of which is selected in dependence on the determined moisture in such a way that the moisture of retained oversized material does not exceed a specified moisture limit when starting material having the determined moisture is supplied to the screening stage, supplying starting material to the screening stage, forwarding retained oversized material arising in the screening stage to the dry-grinding system, and grinding the retained oversized material in the dry-grinding system.
