Performance Analysis of HRC™ HPGR in Manufactured Sand Production

The costs related to comminution in the mineral industry are significant, thus representing main challenge for optimizing such a process. During last few decades, technology of High-Pressure Grinding Rolls (HPGR) has been consolidated as an important alternative circuits, due relatively low operational cost, well high energy efficiency. Due initial capital costs, HPGR applications limited high-capital projects. However, Metso Outotec recently developed low-cost equipment mainly applied aggregates segment. Accordingly, this work aims evaluate performance HRC™ production manufactured sand, based on surveys carried out existing industrial plant. assessment indicates that was adequate sand production. analysis also includes comparisons resulting products Brazilian Standards sands used concrete and filters.
