areas of the burner coal pipes and coal nozzles (Figure 8). Step 4. Properly maintain the classifier. Once the grinding zone is blueprinted and put in first-class condition, the next com-ponent to examine is the classifier. The best furnace combustion performance is governed by uniform coal combustion by the burn-ers and satisfactory coal fineness.

Introduction. By the term "quality of pulverized coal" is understood its fineness (cumulative percentage retained R 0.09 and R 0.20) in conjunction with its homogeneity described by the uniformity (polydispersity) number n.The majority of hard coals combusted in the Polish power sector are bituminous coals of high volatile matter …
Fig. 6 captures the other model outputs – moisture in coal accumulated inside the mill, outlet coal moisture, and coal fineness for 45 degree vane angle. Sieve test performed on 15-12-2013 in the plant is reported and % passing through 200 mesh was found to be 76.2% which closely matches with the simulated result.

Fineness modulus belongs to the number to specify the average size of particle while counting them from lower order sieve size to higher order sieve. Therefore, while measuring coarse aggregate, all sizes of sieves are necessary. Link for Download Excel sheet for sieve analysis of aggregate and to calculate fineness modulus
Therefore, fineness modulus of coarse aggregates = sum (cumulative % retained) / 100 = (717/100) = 7.17 Fineness modulus of 7.17 means, the average size of particle of given coarse aggregate sample is in between 7 th and 8 th sieves, that is between 10mm to 20mm. Limits of Fineness Modulus Fineness modulus of coarse aggregate varies from …

Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75 Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in between the 2 nd sieve and 3 rd sieve. It means the average aggregate size is in between 0.3mm to 0.6mm as shown in below figure.
