HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant. By adding a Polycom high-pressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power consumption by up to 20%.
High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals. The smaller models of the HPGRs are particularly productive in producing manufactured sand for

Crushing (jaw or cone) does not produce the same product size distribution as an HPGR so the pilot plant must include an HPGR. This will also provide scale-up parameters such as the specific throughput and specific force. Currently, these parameters cannot be obtained by any other means. The HPGR suppliers will have a pilot scale unit that they can use to measure these parameters. You do not
The process flow sheet at Newmont Boddington Gold (NBG) comprises primary crushing, closed circuit secondary and tertiary crushing using High Pressure Grinding Rolls (HPGR), ball milling and hydro-cyclone classification to generate a milled product with a P 80 of 150 µm.

Although HPGR technology has been recognized since the late 1980s as a potential powerful tool for heap leaching, operational applications did not proceed until the most recent years. Today, at least four gold operations have implemented HPGR systems from three manufacturers (thyssenkrupp, KHD and FLS) into their crushing circuits. They include
