HPGR technology works by exposing the feed material to very high pressure for a short amount of time. This causes the rock to crack and cleave along the grain boundaries, creating a large number of fines but also forming microcracks in the larger particles. These microcracks create 'canals' to the gold ore particles trapped inside the ...

Far less studied is the effect of feed moisture. This paper investigates both the overall and the specific comminution efficiency of a circuit consisting of a pilot HPGR unit followed by a batch ball mill as a function of the moisture level in the HPGR feed. Forsterite olivine sand (−7 mm) supplied by Sibelco Nordic was used as feed material.

If the HPGR is open at the axial ends of rolls then particles are relatively free to move which can be expected to limit the development of high pressures and therefore the breakage performance. In this HPGR design, cheek plates are included which constrain the axial movement of particles near the ends of the rolls. These are shown in Fig. 2 ...

What is HPGR? Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid volume ...
