Advanced comminution modelling: Part 1 – Crushers ...

2020-12-1  Curry et al. reported ranges for comminution energy of 30–50% for a range of sites but observed that late in mine operating life this could increase to as high as 80–90% as ore grades declined. The general pattern across different sources then is consistently that around 30–50% of direct energy usage is attributed to comminution.
