I think, the SAG/FAG cannot simply be compared with HPGR, taking account of their very different grinding process requirements and results, even the process is dry. As an example, if you expect to grind an ore from 200 mm size to 1 mm size, the use of the HPGR instead SAG/FAG requires the addition of 12 crushing phases, consequently the FAG ...
HPGR vs. SAG Mill Design 1. Original circuit design SAG/AG mills and ball mills (Huckleberry SABC circuit), however very energy intensive and also energy inefficient accounting for 80% of the overall process plant energy (depending on the overall process) 2. Changes to design lead to HPGR and ball mill circuits, thus lowering

Jul 13, 2016 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 ...
Processing of Magnetite Iron Ores - Comparing Grinding Options Although the majority of current steel production is supported by iron ore sourced from high grade haemetite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed.
The resulting power savings translates into an operating cost savings of CDN$0.08/t. The savings in power costs is based upon a power unit cost of CDN$0.032/kWh. For consumables, this reduction was estimated to be about CDN$0.59/t. With respect to capital cost, the HPGR option is CDN$9.45 million (M) more than the SAG option however, within the

hpgr vs high pressure roller mill. HPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining The technology is now widely viewed as a primary milling alternative and there arc a number of large installations commissioned in recent years After these developments an HPGR based circuit configuration would often be the base case for certain ore types such as very ...
This paper reviews recent HPGR applications for the processing particularly of copper, gold, platinum, PGM Ni Cu and iron ores. HPGR technology is discussed with respect to energy efficiency. The harder the ore the greater the energy savings are likely to be. Typical energy savings of 10 20% can be expected when installing HPGR vs. a SAG mill.

Reducing Grinding Energy and Cost - Magnetite Iron Ore Design Case Study A. Jankovic and W. Valery Metso Process Technology Innovation, PO Box 1028, Eagle Farm Qld, 4009, Australia
A synergy of HPGR, pebble and stirred milling can result in a very effective circuit from a capital and operating point of view. It can be expected that highly energy-efficient autogenous processing routes would be further developed and increasingly applied in practice.
The uptake of HPGR technology by metallic mineral processors has involved a number of suppliers but primarily KHD Humboldt Wedag and Polysius for the HPGR machines and ABB for the drive systems. Normally, it is the HPGR suppliers prerogative to choose the drive supplier the end user normally buys the HPGR with the drive systems included.

Generally speaking HPGR is a more efficient comminution method than SAG milling particularly if you factor in rising power costs in light of world governments looking to introduce carbon trading schemes as a method of raising taxes. As mentioned, the cost depends on the circuit design.
