Bagasse Ash

For example, in a case initial specific gravity of bagasse ash having low and high LOI were 2.22 and 2.09, respectively. Whereas after grinding the vale increases to 2.47 and 2.16 for low and high LOI bagasse ash respectively. Specific gravity of bagasse ash is inversely proportional to LOI value. High LOI bagasse ash has lower specific value.
