  • 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.

  • Effects of moisture and coal blending on Hardgrove

    This moisture however has a very important effect on the binding strength of the coal and hence on HGI. It would be possible to have coal with high residual moisture (due to high free moisture added by spraying, dew or rainfall) but actually lower ‘inherent’ moisture caused by long term exposure, which has a greater influence on HGI . 3.4.
