Abstract
This invention relates to a method of diagnosing or controlling a grinding mill for paper pulp, wood chips, or other fibrous materials, by measuring the incremental change in power related to an incremental change in the gap, and using the ratio of the two differences, together with the measure of applied power, as the diagnostic or control parameter.
