  Grindability - an overview | ScienceDirect Topics

  In general, the easier-to-grind coals are in the medium- and low-volatile bituminous ranks. They are easier to grind than coal of the high volatile bituminous, subbituminous, and anthracite ranks. High moisture contents, such as may be encountered in low-rank coals, lead to difficulty in grinding. View chapter Explore book
