HPGR Archives
The PEA outlined a SAG and ball mill crushing circuit with a target grind size of P80 (240 microns), but the more recent test work had shown room for an alternative with a threestage crushing circuit using secondary crushers in open circuit and HPGR as a tertiary crusher in closed circuit. This circuit would target a grind size of P80 between 240300 microns, the company said.

However, 25 mm material from the secondary crushing circuit will be fed to the HPGR, which is regarded as very fine. It is foreseen that for the itabirite ore, the HPGR of Minas Rio will reach 3,240 t/h of throughput operating at a GAP of 65 mm, roll speed of m/s and 80 bar of pressure to obtain the product size distribution illustrated in Figure 16 .

Microcracks in HPGR materials result in improved penetration of leach solution into the grains and thus metal recovery. The objective of this work is to develop a better understanding of ores crushed by HPGR and cone crusher, in terms of microcracks and PSD, and assess the benefits of using HPGR for heap leach projects. The test results can be used in the early stages of the project to develop ...

HPGR vs SAG
HPGR is a machine that plays a role in tertiary crushing, receiving top sizes of about 45 mm and delivering product sizes of around 4 mm (this is achieved by using a classifiion circuit together with the HPGRs). I have seen HPGRs in circuits dealing with throughput of about 1,500 t/h of fresh feed, so you can safely assume that HPGR can be used in a wide variety of tonnages up to the limits ...
