The Effects of Blasting on Crushing and Grinding Efficiency and Energy Consumption Lyall Workman1 and Jack Eloranta2 Abstract Blasting has an important impact on mining and milling well beyond the necessary ability to dig and load the ore efficiently. There is an increasing body of blasting research indicating.Well-consolidated deposits can be mined using conventional drill-and-blast methods. Once blasted, the sandstone is “mucked” using a front-end loader, placed into haul trucks, and transported to a primary crusher. Following crushing, the material may report to a secondary or tertiary crushing plant. The sized material is then transported to.
