2021-9-21 The fragmentation results then were paired with the crusher throughput values, and series of regression analysis were done in order to understand the effects of blast fragmentation on crusher throughput. The analysis includes the relationship between P20, P50, P80, and Ptop values of size distributions and the crusher throughput results.
Improvement of blast-induced 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 Ulf

Quantifying blast fragmentation is useful for measuring blasting performance to determine if the blast has effectively broken the rock mass to enable it to be loaded and that the ore oversize does not exceed the crusher open size.
The rock fragmentation parameter, Rock Quality Designation (RQD), mainly impacts the coarser end of ROM size distribution; as the primary crusher breaks

2021-1-12 sample. This technique is feasible for measuring the crusher product and mill feed but is very expensive and time consuming for measuring ROM. The second method is to assess the size distribution indirectly based on production statistics (eg. extent of secondary breakage, digging efficiency, crusher throughput) that depend on fragmentation.
2012-12-1 The fragmentation level of Blast 4 is categorized as highly efficient fragmentation (Level 3); the practical fragmentation index interval is between 8 and 16. If the in situ block size of the blast is known, the expected mean fragment size interval can be calculated.
2018-9-10 primary crusher is 800 mm. The objective of the study was to improve rock fragmentation to improve productivity of mining equipment. UAV was deployed to study rock faces The limestone rock is classified into four types -- blocky, very blocky, blocky/seamy and disintegrated limestone -- supports blast design

The fragmentation of rock is fundamental to mining. It is the first preparatory stage in the extraction process making rock small enough and loose enough to be efficiently excavated. But this simple statement underestimates how important

Initially the current blast fragmentation needs to be determined (Benchmarked) before any change to the current program is made. The model generated will be calibrated and used to determine what impact any future change (s) will have on the current fragmentation. This will remove a lot of the risk associated with making changes and hoping that
