Henning Knapp, HPGR Process Team Leader for Weir Minerals, said the applications from this equipment have evolved from the cement production days of the 1980s and are increasingly being deployed as tertiary and quaternary crushers in mineral comminution circuits, dealing with tougher ores including iron, gold, copper and diamonds.
neric term that has been widely settled upon is HPGR, high pressure grinding rolls, and is used in this paper as well. It should be noted that each manufacturer has its own registered trade name for their particular HPGR. Quite rapidly, HPGRs were widely installed in cement plants throughout Germany and Europe. Schönert stated
Aug 07, 2019· Starting in the 1980’s, HPGR was first successfully implemented in the cement industry and is now used across a wide range of mining applications. Today, there are more than 200 machines operating in the mining industry around the globe, on more than 150 sites. These energyefficient grinding machines are mostly used for processing iron, gold, copper and diamond ores, although they’re ...
High Pressure Grinding Rolls (HPGR) have increased in popularity primarily due to advantages in both operating and energy efficiency. Relative to the timeline of mining comminution evolution, HPGR can still be considered a young and evolving technology. While a significant amount of research has focused on the benefits of micro
grinding roll technology is not ‘new’, having its genesis in the early 20th century as a method of coal briquetting (Figure 1), and being used in comminution applications since the mid 1980s. However, while HPGR is now commonplace in the briquetting, cement, diamond, and iron ore sectors, its adoption for true hard rock comminution duties ...
One roll is fixed to the frame of the machine, the other allowed to move against a set of hydraulic rams. Grinding force is provided via hydraulic pumping system and assisted by nitrocharged accumulators. The roller press is designed to operate in choke feed conditions. Feed material is introduced into the gap between the rolls.
