Abstract Liners in grinding mills not only protect the mill shell from the aggressive environment inside the mill, but they also play a significant role in the efficiency of grinding. The design of mill liners dictates the charge trajectory and hence the grinding efficiency. The common approach in...

ABSTRACT Blasting plays a major role in the fragmentation of rock in open pit mining, which is then crushed and processed before the final product is obtained. Tailoring the blasting method to suit rock mass characteristics can lead to significant improvements downstream. Mine to Mill is a method...
