high moisture coal grinding

Effect of moisture on energy-size reduction of lignite
· Reducing the moisture content of coal made the grinding easier. For samples with the moisture content equal to or below the air-dried level the mass fractions of the top size fell to approximately 14.61 after 6 min of grinding while for coal sample 1–3 the values were higher 42.29 28.23 and 24.73 respectively.
