Analysis of blasted rocks fragmentation using digital ...

2017-8-24  Analysis of the F 80 value obtained from fragmentation analysis of block no. 2 indicates that this value is equal to 568.15 mm, which is smaller than the crusher’s entrance (60 cm). Although this pattern yields a suitable F 80 value, it increases drilling costs by adding to the number of blast holes, which is not economically desirable.

Stemming Plugs Agg-Net

2022-1-5  The average primary crusher throughput of stone from the Vari-Stem plugged blasts was 879 tons/h, representing a 3% increase in stone throughput at the primary crusher. Conclusions. The Vari-Stem stemming plug trials at Rich Hill Quarry resulted in performance benefits in terms of fragmentation and increased primary crusher productivity.

BEST PRACTICES IN DRILL AND BLAST - IQPC Corporate

2017-5-9  FRAGMENTATION The key objective is to deliver a product that is broken well enough to maximise crusher throughput. That positions fragmentation as the main infl uence to performance of downstream activities in a mine. As a consequence, the profi t of a mining operation can be greatly improved through optimised fragmentation.
