Optimise your pebble crushing with HPGR. High Pressure Grinding Rolls offer an energy-efficient way to crush pebbles and alleviate bottlenecks caused by mills struggling to reduce the stubborn particles of hard ore. Whether recirculated through primary milling or separated and sent to a dedicated downstream pebble mill, pebble crushing is an ...

Other points of comparison between HPGR and mills. In addition to their reduction qualities, High Pressure Grinding Rolls have a few less-important advantages over conventional mills. For example, they occupy less physical space compared to most ball and rod circuits, and vibrate comparatively little thus requiring less supports.

A second source of uneven feed to the HPGR can be segregation, where one side of the HPGR is mostly fed with coarser particles, while the other side receives more fines. Figure 3 shows a schematic illustration of feed segregation prior to the HPGR (Van der Meer & Maphosa, 2011). Similar to the impact of the uneven feed in the

The high pressure of HPGR's "bed-breakage" creates micro-cracks in the ore, promoting improved mineral recovery at coarser size fractions. This means less leaching acid is required and percolation periods are shortened, reducing costs and maximising recovery in less time. In the diamond industry, the HPGR acts as a selective grinder ...
