10 microns. Since conventional ball mills are highly inefficient in this fine size range, the stirred ball mill has been proposed as a more suitable means for ultrafine grinding. A five inch diameter mill has been designed and constructed to investigate the milling characteristics of stirred ball mill grinding using an Elkhorn seam coal.

mill. When the coal particle sizes are reduced to about 15.0 μm in diameter, a dynamic balance between pulverization and aggregation occurs (Cui et al., 2008). As a result, when coal particles are smaller than 15.0 μm, there will be no further particle size reduction in ball mills, but the energy consumption dramatically increases. The
