As the amount of S i or a T values increases, the effective breakage increases, and breaks very fast in the undersize of original particle size. The experimental values show that grinding is faster for samples as Bond grindability values (G bg) increase. Thus, G1 is faster grinding at the original particle size than the other samples of limestone.

Since the advent of ball mills, the research of particle breakage properties has always been a hot topic. In the milling process, the particle breakage process is like a black box, and hard to quantify the breakage behavior. In fact, the particle breakage property (size reduction) is a key factor, which directly affects the grinding effect.
