One of the workhorses of the minerals industry is the autogenous grinding (AG) mill and its derivative the semi-autogenous (SAG) mill. These are relatively well understood, but not so Scrubbers.
A typical SAG-HPGR-Ball mill circuit suggested by Patzelt et al. [6] is shown in Figure 9.6, where the pebbles from the SAG mill are crushed in the high-pressure grinding rolls. It is a general observation that SAG mills are helpful for grinding where wide variations in the grindability of ores are experienced.

• a crushing circuit including high pressure grinding rolls (HPGR) at Argyle Diamond Mine. Recent feasibility studies for the Boddington Expansion Project have considered the use of HPGR for hard rock multi-stage crushing and ball mill circuits at high tonnage rates (Parker et al, 2001).
The high pressure grinding rolls (HPGR) is a relatively new type of equipment, very efficient in terms of energy savings. There are several configurations for comminution circuits that utilize the HPGR technology replacing either AG / SAG grinding, or crushing/grinding stages or even as surface generation step prior to iron ore pelletizing.

TO DETERMINE WORK INDEX FOR HIGH PRESSURE . GRINDING ROLLS . ABSTRACT. The use of High Pressure Grinding Rolls is gaining significant interest as a replacement for SAG milling in the . comminution of hard rock ores because of the potential for reduced costs in terms of energy and grinding ball consumption.
The Huckleberry mine, located in British Columbia, produces roughly 40 million lb/y of copper. A comprehensive energy and cost study compared an existing SAG mill-based circuit at the Huckleberry mine with two proposed circuits involving comminution technologies that are associated with energy efficiency: high-pressure grinding rolls (HPGR) and high-speed stirred mills.
Application of more efficient grinding technologies developed in the last 20 years, including high pressure grinding rolls (HPGR) for fine crushing and stirred milling for fine grinding, has ...
