2nd February 2021. High pressure grinding rolls (HPGR) offer the most energy efficient comminution for gold ore, allowing mines to increase their throughput and operate more sustainably.

The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through ...

Where HPGR technology has replaced traditional methods of crushing and grinding (e.g. SAG or ball mills), it has: Provided excellent throughput capacity and energy efficiency. Decreased energy consumption by up to 40%. Substantially reduced water consumption. Reduced recirculation and wear within crushing and grinding circuits.

The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.

The material is fed to the HPGR by gravity and dragged into a compression zone between the rolls. The nip angle (α) represents the point in which the roller force starts acting on the material, thus starting the packed bed compression.The nip angle is dependent on the roller diameter and several material properties such as particle size …

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 ...

Why HPGR? The energy-efficiency of crushing and grinding is an increasingly important issue across all processing industries requiring comminution or size reduction of material. Today, high energy costs coupled with the worldwide initiative to reduce CO2 emissions have made state-of-the art HPGRs indispensable in many processing industries.

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
