A defined mass of coal (50 g) with a specific particle size range (1.18 and 0.6 mm) is then ground and sieved, and the mass fraction of the particles passing through the 75-µm sieve is determined. From this value the HGI is calculated. The lower the HGI value the harder and less grindable the hardgrove grindability ball millGreater is Hardgrove Grinding Index easier is the material grindability and requires less power for grinding2-5 .The objective of this study was (a) to suggest model to describe comminution for wide range particles size (b) suggest schemes to reduce power consumption in ball mill operation.
