System and process for monitoring wear on components of a grinding mill

A process, comprising:

• detecting measurement data on a wear condition of a component of a grinding mill and on an operating state of the grinding mill periodically or continuously over time;
• assigning the measurement data to at least one parameter on the wear condition of the component of a degree of wear of the component and the degree of wear to a maintenance loss, corresponding to a yield loss based on technical maintenance of the component;
• deriving from several pieces of measurement data detected at different times a future wear condition at a time in the future;
• assigning the future wear condition to a future degree of wear and a future maintenance loss;
• assigning the measurement data on at least one parameter of the operating state of the grinding mill a grinding yield value that specifies a yield from operation of the grinding mill;
• determining a grinding yield loss relative to a target yield level of the grinding mill;
• deriving a future operating state from several pieces of measurement data detected at different times;
• deriving a future grinding yield loss at a future time;
• optimizing a maintenance time in the future, by establishing as the future maintenance time that time at which the future maintenance loss corresponds to the future grinding yield loss;
• and
• controlling an operation of the grinding mill based on the future maintenance time.
