pressure grinding rolls (HPGR) (Schonert, 1988 and 1991). Additional benefits have been linked to the application of the HPGR, such as differential comminution in diamond-bearing kimberlite, grinding media elimination when replacing SAG mills, and improved performance in leaching and flotation resulted from micro-

(HPGR) as an alternative technology to the conventional semi-autogenous grinding (SAG) milling process for the Morrison Project. The processing plant is designed to operate at 30,000 t/d capacity with an availability of 92%. Results of the trade-off study indicate that the application of HPGR's to the Morrison project

The first commercial application of HPGR was in 1985 and its success resulted in increasing numbers of applications since then, particularly in the cement industry ( Kellerwessel, 1990 ). Tube mills having multichambers are traditionally used for cement grinding either in open or closed circuit operations.

High pressure grinding rolls are an energy efficient grinding solution, and now has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market. Increased circuit efficiency and capacity - flanges direct material to the crushing zone, maximizing the amount of ore crushed.

Secondary crushing in combination with tertiary HPGR application, both in closed circuit configuration, potentially allows to substitute AG or SAG grinding when just considering particle size, i.e. getting a primary crushed ore down to a suitable size for ball mill grinding. For the selection other factors need to be considered, such as ore ...
