Four HPGR Polycom-24/17 manufactured by Thyssen-Krupp Resource, each equipped with two 2500 kW motors, came into operation in Cerro Verde mine in 2006 and have the longest service life by now. Mogalakwena began using one HPGR Polycom-22/16 in 2008, and four HPGR Polycom-24/17 have been operated in Boddington mine since 2009. UDC 622.732
Minerals | Free Full-Text | Methodology and Model to Predict HPGR
1029;Sizing High-Pressure Grinding Rolls (HPGR) requires a large quantity of material, making it not attractive and costly to be considered for new mining projects regardless of their energy consumption reduction benefits. Ongoing efforts are being made at the University of British Columbia to predict the behaviour of the HPGR using a low …

Breaking down HPGR technology with Weir - miningmagazine
625;Breaking down HPGR technology with Weir. High pressure grinding rolls (HPGR) have emerged as an increasingly attractive alternative in recent years to conventional crushing plants or AG/SAG milling. Craig Guthrie. HPGR reduces particles by crushing the feed between two parallel rollers. 25 June . Mining Magazine editor …
Other points of comparison between HPGR and mills. In addition to their reduction qualities, High Pressure Grinding Rolls have a few less-important advantages over conventional mills. For example, they occupy less physical space compared to most ball and rod circuits, and vibrate comparatively little thus requiring less supports.
Potential of High-Pressure Grinding Roll (HPGR) for Size - Springer
316;Abstract HPGR has been found to be efficient size reduction equipment compared to conventional size reduction equipments due to its potential processing benefits in terms of energy savings, improved exposure or liberation and particle weakening. The objective of the current work is to study the optimization of different process parameters …
