Abstract
Disclosed herein is a method and system for grinding fragmentary starting material, in particular ores, with a dry grinding system. An embodiment of the method includes the steps of determining the moisture of starting material for a certain period of time, preparing at least one screening stage, the cut point of which is selected depending on the determined moisture in such a manner that the moisture of a screen oversize does not exceed a predetermined moisture limit value when starting material having the determined moisture is fed to the screening stage, feeding starting material to the screening stage, transferring a screen oversize arising in the screening stage to the dry grinding system, and grinding the screen oversize in the dry grinding system.
