Improved characterisation of ball milling energy

Jan 15, 2018 The HPGR-ball mill circuit was estimated to require 75% of the energy of a standard Semi-Autogenous Grinding (SAG) mill circuit. Even with an anticipated greater capital cost, the HPGR-ball mill circuit was found to give significantly better financial returns in all cases investigated in the feasibility study ( Ballantyne et al., 2016 ).
