The method used to reduce the gross sample to the analytical sample must maintain the integrity and repre- sentativeness of the sample while meet- ing the particle size and weight require- ments as specified by the particular analytical methods. The preparation of a gross sample for coal analysis requires several process- ing steps.
the sample (the one hour collection period must be a full hour of coal flow). The sampling system should be set to collect at least the sample mass specified in the standard during one hour test periods. All of the proper protocols for sample preparation and analysis must be used and documented, and the OLA data collection must be in accordance
The normal preparation procedure requires that each air-dried coal sample pass through a jaw crusher; one subsample (split) of the crushed material (2 to 4 mm, or 5 to 10 mesh) is then taken for the ultimate and proximate analyses, and another split is reduced to approximately 150 m m (100 mesh) by a vertical grinder for chemical analysis.
coal samples, such as brown coal, the sample preparation step becomes even more important in ensuring reproducible analysis results. The fineness of the sample can influence the standard deviation of the analysis results, as will be shown in this article using brown coal as an example. In general, using a sample divider to
