Abstract. Grindability index of coal is an important technological parameter to understand the behaviour and assess the relative hardness of coals of varying ranks and grades during comminution. This is usually determined by Hardgrove Grindability Index (HGI), which involves requirement of a costly grinding equipment and accessories not readily ...

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
