17/11/2012 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
To classify coal particles to the required level of fineness, normally 70 % through 200 mesh and less than 2% on 50 mesh Coal parameters affecting pulverizer output While selecting a pulverizer, the coal characteristics play an important role. The Hardgrove
Poor Coal Fineness often yields poor distribution as large coal particles & air mix to form a (2) phase mixture which will not homogenize. Good Fineness Creates a homogenous & balanced mixture which behaves more like a gas than a (2) phase mixture of air & fuel
