A higher Hardgrove index indicates the coal is easier to grind 50 HGI normally is taken for calculating the base capacity of the mill When coal with HGI higher than 50 is fed to the pulverizer the output will be higher than base capacity and below 50 HGI the output will be lower The total moisture in coal has a high effect on mill outputOct 21 2018 The main coal property which has the main influence on the mill power consumption and capacity is the hardness determined by the ‘Hardgrove grinding index’ (HGI) Usually the higher is the HGI the easier it is to grind the coal with consequent lower power consumption and
