importance of pulverization of coal

USGS Bulletin 1823 Preparation of Coal for Analysis

The pulverization of bulk coal samples from the field serves both to homogenize the coal, which typically is quite heterogeneous, and to reduce the material to small particles needed for rapid ashing and dissolution. Thus, the comminution process is of critical importance, and all aspects of the laboratory arrangement and of procedures for
