When a quarry wants to optimize, it's easy to concentrate on obvious value-creating events, such as crushing chamber performance. But these only account for about 5% of the entire quarry process. The remaining 95% of activities do not create value – minimizing them gives you excellent potential to boost profitability. Drilling and blasting:
