Grindability was shown as the ratio of ΔS v to E. As a result, the grindability indices of 17 samples of limestone from 14 quarries were ranging 8-18(cm 2 /cm 3)/(kg.m). These values of limestone were larger than those of quartz, feldspar, fluorite, kaolin and bentonite, and smaller than that of talc, and two to five times as large as that of ...

Grinding energy requirement and so the grindability nature of the material (limestone in this case) should be addressed in detail. In order to address the comminution behavior of rocks, mostly addressed index is HGI, i.e. Hardgrove Grindability Index.

During the determination of the Hardgrove Grindability Index (HGI), 50–50 g limestone samples from the 0.63–1.25 mm and 50–100 μm particle size fractions were ground to 60 mill speeds, and then the ground material was divided into 0.071 mm sieve fractions.

This study aimed to investigate the effects of volumetric powder filling on the Hardgrove grindability index (HGI) based on limestones. First, it was investigated whether there was a good relationship between the HGI and the G bg for three different volumetric powder fillings using six different limestones.
