  • Effects Of Mill Performance On Unburnt Carbon In Coal

    Effects Of Mill Performance On Unburnt Carbon In Coal

    In addition, the primary air flow rate through the mills is above 100 kNm 3 /h, whereas the historical operational values were between 80 to 100 kNm3/h. The higher primary air flow reduces the residence time of coal particles in the mills, reducing the grinding time and thus resulting in coarser coal particle sizes exiting the mill.
