  • BEST PRACTICES IN DRILL AND BLAST

    Under-blasting can lead to signifi cant amounts of oversize rock which cannot pass through the crusher and will require size reduction before being taken to the crusher. Conducting fragment break-up is costly and needs secondary blasting or use of a mechanical hammer for rock disintegration. UNIQUE FACTORS THAT INFLUENCE FRAGMENTATION

  • The Effects of Blasting on Crushing and Grinding

    The size of fragments is the “seen” part of blasting results. It is very important in crushing as it effects production and downtime. Overly coarse fragmentation will reduce primary crusher throughput. Coarse material will lead to more downtime for clearing crusher bridging and plugging.
