Abstract

An example method for operating a plant, which has at least one assembly with a rotating surface that wears to an increasing extent during the operation of the plant, may involve evaluating a wear state of the rotating surface of the assembly. Based on the wear state of the rotating surface, a manner in which the plant is operated may be modified to prolong the running time of the assembly until, for instance, a next-scheduled service or maintenance interval. The modified manner of operating the plant may be adapted to the wear state of the rotating surface. Several examples of such modifications include changing a quantity of water sprayed onto material to be comminuted, changing a quantity of grinding additive added to material to be comminuted, and/or changing a contact pressure of a grinding roll of the assembly.
