Why crushing and especially grinding can dominate plant electrical demand.
Mine-to-refinery note: mineralogy, site conditions and the approved flowsheet determine real operating requirements. This site explains system relationships rather than field procedures.
What this topic covers
Why crushing and especially grinding can dominate plant electrical demand.
Core mine-to-refinery ideas
Breaking rock requires energy that rises as particle size is reduced.
Energy-efficient flowsheets avoid grinding material finer than needed for liberation.
Energy intensity should be compared with tonnes processed and recovery achieved.
Important tradeoffs
Finer grinding can improve liberation but increases energy and can create difficult fine particles.
Measurement and accounting
Classification and screening help control the size distribution entering downstream processes.
Lifecycle perspective
Machine operation, clearing and lockout procedures are not provided.
