MODELLING FINES IN BLAST FRAGMENTATION AND ITS

• 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. This technique is feasible for measuring the crusher product and mill feed but is very expensive and time consuming for measuring ROM.
