Improving energy efficiency in comminution

1-10-2018Generally the biggest benefits (10 to 20 percent increase in throughput) are seen for the hardest ore Softer ore benefits much less and sometimes it is necessary to reduce the intensity of the blast in these cases to ensure an optimal ROM for downstream processing One very important point is that more blasting does not mean less crushing
