13.1.Fineness : 13.1.Fineness Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance.
