Limestone grindability in terms of HGI and a new approach ...

In this study, limestone samples (a total of 108 sample) were collected from two limestone quarries. The collected samples were initially in the form of palm sized and they were crushed to −2.36 mm. Grinding experiments were conducted in standard HGI (Hardgrove Grindability Index) mill and Ring mill.

Grindability - an overview ScienceDirect Topics

Grindability is normally measured by determining the number of revolutions in a pulverizer that are required to achieve a given size reduction. This is an indirect measure of the amount of work required for that size reduction. Grindability increases slowly to a maximum at ∼90% carbon and decreases rapidly beyond this point.

Grindability of Limestone by the Modified Hardgrove

2017-7-3  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 ...

The Influence of Limestone Additions on the Rheological ...

The variations in the yield point and plastic viscosity showed the “lubricity power” of the smaller particles (below 10 μm). Their amount is increased by the relatively greater grindability of the limestone concerning the clinker. The limestone additions seem not to change the water retention value.
