The HPGR complements the operational life of the cone crusher liners, whilst generating a finer product that frees up the circuit's milling capacity. Similarly, when placed after a (S)AG mill, a significant quantity of oversized or tramp materials can disrupt HPGR operations.

Figure 5: HPGR crushed particle. Source: Baum (1997) Moats and Miller (2010) examined the particle damage and cracks in comminution products by jaw crusher and HPGR unit respectively utilizing High Resolution X-Ray Micro-Tomography (HRXMT). The crack density and networks can be viewed in three dimensions using HRXMT data as shown in Figure 6.

HPGR wear vs conventional mills. Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis.

NLMK began implementing HPGR technology in each of the plant's four process lines in 2016. The first four grinding rolls supplemented traditional cone crushers and ball mills, and enabled the plant to boost the productivity of the sections by 12.5% and to grow iron .

"Rotating mills, conventional crushers and HPGR's can be used depending on the rock strength. If the multiple of the drop test parameters 'a' and 'b' (AxB) is • Above 200 use a scrubber • Above 60 use AG milling • Above 40 use SAG milling • Above 25 use HPGR AxB very rarely goes below 25.

Simulating HPGR has two differences from a classical SSBM circuit with cone crushers: first is that the crusher product tends to be finer (~4 mm versus 9 mm) and the nature of the product is different. To simulate an HPGR and ball mill circuit, choose the HPGR - BM flowsheet and the Bond/Rowland single stage ball mill model.

The evolution of HPGR technology • Tertiary crusher followed by a ball mill or VERTIMILL • Quaternary crusher followed by a ball mill or VERTIMILL • In a pebble crushing circuit for a SAGAG mill Suitable ore types The HRC HPGR is ideal for crushing hard HRC HPGR Applications rock with relatively low moisture content and can provide superior results in the size

The Copper Mountain mill flowsheet is currently a conventional two-stage crushing, SAG, pebble crusher, ball milling, and sulphide flotation circuit design. The current capacity supports 40,000 t per day of ore processing. The 45ktpd Expansion that is currently underway will add a third ball mill in parallel with the two existing ball mills.

Where HPGR technology has replaced traditional methods of crushing and grinding such as SAG or ball mills, customers have seen energy savings of up to 40%, and substantially improved mineral liberation. Find out more about the Enduron HPGR:

Note, HPGR is a crusher used to crush ore, not to mill ore. Therefore HPGR are part of the crushing plant and incorporated only if the ore characteristics permits. The HPGR can be used in hard rock mining but not on soft ores or wet sticky ores and wet climates. …

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

Like trends in mills, larger equipment sizes continue to evolve. Freeport's Morenci operation, for example, commis­sioned a 3.0 x 2.0-m HPGR (called the hydraulic rolls crusher, or HRC) in an expansion mill circuit in 2014.
