and milling operations. Therefore it is necessary to measure the size distribution of rocks at different stages of a mine-mill process such as: • ROM fragmentation (after blasting) • after primary crushing • after stockpile as mill feed. The traditional method of assessing the size distribution of rocks is to sieve a representative sample.
