The effect of major element oxide and moisture loss on grindability of Afsin-Elbistan low-grade coal
In this paper, the influences of major element oxides and moisture loss in coal on its grindability were examined using the Hardgrove equipment. The major element oxides in the coal could be a predictor of HGI. If CaO content in the coal was high, the grindability of coal could be easier. The moisture loss in the coal had a strong effect on the grindability property. The pH could be a good indicator to predict and classify HGI. If the pH is lower than 9.5, HGI is also lower than 53 and those type of coal was classified as heavily grindable.
