activities, such as drilling, blasting, loading, hauling, crushing and to some extent grinding. Optimization of rock breaking by drilling and blasting is sometimes understood to mean minimum cost in the implementation of these two individual operations. However, a minimum cost for breaking rock may not be in the best interest of the overall mining system. A little more money spent in the rock

Ball mill media optimization through functional

The cumulative grinding rate through the size of interest is the identical parameter as the ball mill grinding rate calculated from the functional performance equation. Its maximization is the technical optimization criterion for ball sizing studies. Plant ball mill preferential retention of coarser particles, ignored by most population balance modeling, confounds interpretation of plant

Increased Productivity Through Improved Blast Design

simulation studies explored the impact of blasting alternatives, changing blast patterns and explosive types. Subsequent trial blasts resulted in ROM fragmentation being clearly finer at the primary crusher. Compared to the benchmark trial, this resulted in approximately 15% more throughput for the test case;

Safety of engineered structures against blast vibrations

01/04/2016· For optimization of various parameters associated with blasting, several blasts were monitored by varying burden, spacing, powder factor, charge per hole, etc. Based on these observations, blasting patterns were optimized and used for rock excavation. Typical blast design parameters used at site are shown in Table 4. To minimize the damage to

How to ensure energy efficiency in mining 2/4: Process

10/12/2018· liming has numerous case studies in which changes in drill and blast designs have led to increases in downstream throughput by 5-20%. Increasing throughput through a SAG mill generally requires feeding it with more fines. If these can be generated in the blast, then it is a much more cost-effective way of achieving a higher SAG throughput
