Primary Crusher Optimisation for Improved Comminution …
The first step in the mining and processing of nearly any mineral ore is comminution. Since the oil embargo of 1979, the mining companies have been striving to reduce energy consumption and costs. The first serious step was the introduction of in-pit crushing in the early 1980s. With in-pit crushing accepted as a standard design mode, the energy saving emphasis turned to …

Advanced comminution modelling: Part 1 – Crushers
Curry et al. [5] 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 ...
