Jul 1, 2010 Crushing and grinding processes have undergone significant changes over the last 20 years. These adjustments have HPGRs are emerging as an important new comminution process in mineral processing circuits, primarily because they offer substantial energy savings. There is good evidence from

In industries supporting mining and milling operations, crushing plays an important role in reducing particle sizes of rocks and ores. To reach desirable end product size, the feed material endures a few crushing stages that form a circuit. A crushing plant system consists of a combination of unit operations for storing, feeding,

It is also a cheaper and more efficient process, compared to both crushing and grinding. One of the most valuable aspects of blasting is the generation of very fine particles (e.g., smaller than 12mm) that will pass through the primary mills and onto the secondary ball mill circuits, alleviating a common bottleneck. Modifying
