18th Relationships Between Bond's Grindability (G ) and ...

2009-9-17  The dry grinding of" size intervals of limestone samplesshowed that these samples followed the first-order breakage law with constant normalised primary breakage distribution function. The values of the primary daughter fragment distributions and the values of a in S^orX" are different in the samples of limestone. As the amount ofS, or ci]- values increase, the effective breakage increases, and breaks as very fast in the undersize of original particle size. The experimental values show that grinding is faster grinding for samples as fraction of bond grindability values (GhC) increase. Thus, Gl is faster grinding of original particle size than other samples of limestone.
