According to one study, the grinding process alone accounts for approximately 40% of total power con-sumption in a mine complex (Ballantyne et al., 2012). A ball mill employs steel balls to generate a grinding ac-tion, i.e. ore particle comminution via impact and abra-sion with steel balls, and is a key component of benefi-ciation plant production.
