In this research, the effect of different parameters of coal composition (coal chemical properties) were studied, to estimate the coal HGI values index. To estimate the HGI values artificial neural networks (ANNs) and linear multivariable regression methods were used for 400 data. In this work, ten input parameters, such as moisture, volatile matter (dry), fixed carbon (dry), ash (dry), total ....

Coal Analyzes - Hardgrove Grindability Index (HGI)The grindability feature is derived from basic material properties such as crack, hardness and flexibility and is used to calculate the resistance of coal to grinding. When coal is used as powder fuel, its grindability feature is utilized. Hardgrove index is one of the tests applied in coal preparation plants to determine the grindability of coal.
