A typical laboratory sample of coal often consists of 10 kg or more. When dealing with rather inhomogeneous materials like lignite it is not enough to take one of the big lumps and crush it to obtain a few grams which can then be used for analytical processes such as the determination of the calorific value or sulfur content.

This test method provides a means for assisting in the evaluation of pulverizers and pulverizer systems in terms of fineness specifications. It may also be used to confirm the influence of coal fineness on combustion performance and to evaluate carbon loss. By consent among interested parties, it may be used for evaluation of coal fineness in preparation, pneumatic transfer systems, etc.

Collecting coal samples using an isokinetic probe provides the best data describing actual operating conditions inside the coal pipe. Source: Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance.

The coal particulate sizes were plotted against the Rosin and Rammler [8] formula to verify the representativeness of the coal sample and sieving (Figure 8). Theoretically, the mass flow of coal can be more uniform by increasing the coal fineness ( decreasing coal particulate size).
