Grinding media is used in the process of extracting minerals from ore, particularly in the fast growing copper and gold industries . Ore particles must be ground down to sufficiently small sizes so the contained metal species become ‘liberated’; i.e. free from gangue materials, prior to subsequent concentration processes . Grinding is carried out in large horizontal tumbling mills, partially filled with steel balls or rods (grinding media) . Mills require continuous refilling with new grinding media as they get consumed . Consumption of grinding media is related primarily to the volume of ore processed For personal use only and ore characteristics (abrasiveness, particle size and specific energy input) 9 Grinding media fundamentals Crushers No balls SAG Mills – single stage 4”-6” balls “Moly-Cop provides SAG Mills – multi stage full range of sizes 4”-6” balls from 1” – 6” balls” HPGRs No balls Rod Mills 3”-4” grinding rods Ball Mills 1”-4” balls Tower Mills 0.5”-1.5” balls IsaMills <0.1” balls For personal use only Small balls Large balls 1 10 100 1,000 10,000 100,000 1,000,000 Particle size, μm10 Source: Moly-Cop Moly-Cop grinding media .
