In the past plants would invest in a second ball mill to run in parallel with their current one to add the additional capacity but this is not always an energy efficienty way of tackling the problem Recent research by Malcolm Powell Sam Palandiandy at the JKMRC showed that using a tertiary vertimill to increase circuit capacity can be 25% more energy efficient compared with adding extra
