  • Analysis of blasted rocks fragmentation using digital

    Blasting is the first step to reduce rock size, which is followed by the crushing and grinding phases The efficiency of these operations depends on size distribution of blasted rocks Therefore, measurement and analysis of fragmentation of blasted rock masses are highly essential Many methods are available for assessment of blast fragmentationCrusher Product Energy $ Relative Energy and Costs Specific energy kwh/t Energy factor Cost factor Drill and Blast 01 – 025 1 1 fragmentation performance of the rock mass • Jointing/Bedding • Defines maximum fragment size • Influences transmission of stress waveFragmentation Management for the Downstream ValueRock fragmentation is generally assessed either by direct methods involving sieving analysis or indirect methods involving observational,(PDF) Rock Fragmentation by Blasting – a review

  • Improvement of blastinduced fragmentation and crusher

    Improvement of blastinduced fragmentation and crusher efficiency by means of optimized drilling and blasting in Aitik ACKNOWLEDGMENTS The thesis project presented in this report was conducted in Boliden's Aitik mine; thereby I wish to gratefully thank Boliden Mines for their financial and technical support I would like to express my very great appreciation to UlfCrusher design fragmentation results are shown in Figure 2 as an envelope formed by fines design and coarse design curves developed by the use of PSD Therefore, if the predicted and actual fragmentation curves fall within the finescoarse envelope this indicates that the ideal/desired fragmentation profile is achievedDetermination of optimal fragmentation curves for aFollowing each blast, the much pile dimensions were documented and an optical fragmentation analysis was conducted throughout the excavation of the shot rock The primary crusher throughput was also monitored Previous studies have demonstrated a direct correlation between improved fragmentation and increased productivityStemming plugs improve blasting, productivity Quarry
