Jul 31, 2020· Therefore, a target of % surface moisture (S.M.) in ground coal (we may call it as fine-coal) is necessary to fix while grinding. The recommended residual moisture (S.M.) content depends on content of hygroscopic moisture (I.M.) in the raw coal. And target moisture in ground coal is suggested to maintain 1–2% more than inherent moisture.
