Horizontal roller mill Horomill ® application versus. The specific energy consumptions for the HPGR and ball mill were determined based on the mill throughput rate and circuit capacity as 15 kWh/ton and 23 kWh/ton respectively during production and of the Horomill to be 201 kWh/ton...
Fine-grinding and ultra-fine grinding of ore or concentrates in conventional ball mills results in energy consumptions that increase exponentially with product fineness. Wipf (2009) presented a flowsheet in which he proposed the installation of HPGR ahead of the Aerosion "Disintegrator" for ultra-fine grinding of ores and/or concentrates.
HPGR was tested in closed circuit with an air classifier to produce a fine product. This was benchmarked against HPGR with dry screening followed by ball milling. Logged power input was compared with power input calculated from Bond tests. HPGR with air classification used 30% less power than HPGR with dry screening.

HPGR Ball mill Merensky UG2 PGMs Liberation ... of the HPGR is the 20–50% reduction in energy consumption, the 20–30% increase in throughput, as well as the signiﬁcant reduction
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.
How HPGR compares to conventional milling. Aug 19, 2019 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 This …
Thus, the ball mill consumes 12.89 kWh/t, more energy than the SAG mill in producing the final product. 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 …

HPGR is mainly used in pellet feed to increase the specific surface area of the particles, in order to allow for strong pellets. This is in contrast to normal comminution applications, where size reduction is the main purpose. In pellet feed application, HPGR is competing with dry ball mills, which consume more energy.
Put simply, some of the power savings of more efficient comminution is used to transport material through the various unit operations of crushing, HPGR milling, and screening. Media wear is much less than an SAG circuit in terms of total volume (balls and liners) or as unit consumption in terms of kg/kWh or kg/t.
Multi-stage crushing plants, including high pressure grinding roll (HPGR) circuits, require more materials handling equipment than SAG and ball mill circuits. A temptation exists to neglect the energy consumption of materials handling when doing desktop comparisons of HPGR versus SAG milling circuit...
