Fuel line fineness should be 75% or more passing a 200-mesh screen and a maximum of 01% remaining on the 50-mesh screen , The next step in this plant is to upgrade the mill to improve coal .
With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 995% or higher
Coal fineness is a relative measurement of particle size distribution typically applied to the product leaving a pulverizer Standardized wire mesh screens are stacked and used to ,
With near 0% remaining on the 50-mesh sieve, at least three points are needed on the Rosin-Rammler Chart to plot the fineness results Four sieves of 50, 100, 140, and 200 mesh are recommended for fineness sampling Fuel line fineness should be 75% or more passing a 200-mesh screen and a maximum of 01% remaining on the 50-mesh screen
