Bilen, C. Schmidt Hammer Rebound (SHR) values as a guide for the initial estimates of limestone uniaxial compressive strength (UCS) and Hardgrove grindability index (HGI). Arab J Geosci 14, 2184 (2021). https://doi/10.1007/s12517-021-08421-4
Determination of Bond Work Index of Lucky Cement …
Among all seven samples collected from the different faces of quarry, Bond work index of limestone Face-4A results less than 20kwh/t, remaining 6 samples are marked as hard rock …
Limestone grindability in terms of HGI and a new approach …
Schmidt Hammer Rebound (SHR) values as a guide for the initial estimates of limestone uniaxial compressive strength (UCS) and Hardgrove grindability index (HGI) C. …
Grindability of Limestone by the Modified Hardgrove …
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 …
Determination of Bond Work Index of Lucky Cement …
Among all seven samples collected from the different faces of quarry, Bond work index of limestone Face-4A results less than 20kwh/t, remaining 6 samples are marked as hard rock because of high energy consumption and low grindability rate.

Hargdrove Grindability Index (HGI) and calculated …
... terms of the Bond work index, limestone behaved as the easiest-to-grind and sand and basalt as the hardest-togrind materials. These results are correlated well with the Hardgrove based Bond...
Energy-Model and Life Cycle-Model for Grinding Processes of Limestone …
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.
Limestone grindability in terms of HGI and a new approach …
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.

Limestone grindability in terms of HGI and a new approach …
Hardgrove grindability index (HGI) values of clinker and colemanite are 51.81 and 99.62, and Blaine fineness values are 920 cm2/g and 2430 cm2/g, respectively.

A new model between the Bond and Hardgrove grindability …
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.

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 ...
