Product size distribution function influence on interpolation
Differences up to 6,2% in the Bond ball mil work index can be observed due to different siz distribution in P 80 calculation.. 13 ores were tested using the Bond ball mill grindability test, obtaining P 80 using different interpolation functions. Rosin Rammler's model showed the best behavior, so its use must be not only suggested, but recommended.
