Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.

Abstract The introduction of large semiautogenous mills to grind larger pieces of ore necessitates the use of large diameter grinding balls. Grinding balls as large as 127 mm (5 in) in diameter are not rare. The increased height of fall of such grinding balls in these larger mills results in severe impact between the grinding balls and also between the grinding balls and the mill liners. The ...
