Description

Fragmentation characteristics influence mucking productivity, crusher throughput and energy consumption, plant efficiency, yield and recovery, or the price itself of the end product in the case of industrial minerals and aggregates. Reliable, quantitative measurements of fragment sizes are instrumental in controlling and optimizing the blasting results. Measurement and Analysis of Blast... Read more
