Grindability of Limestone by the Modified Hardgrove Method

 · 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 ...
