High pressure grinding rolls (HPGR)
Robust HRC™ high pressure grinding rolls (HPGR) High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed ...

HPGR model verification and scale-up
The high pressure grinding rolls (HPGR) is a relatively new comminution device that offers realistic potential in dramatically reducing comminution energy requirements. As such, it is viewed as an alternative to the existing, less energy efficient processes such as semi-autogenous (SAG) and ball mills.

Flowsheet considerations for optimal use of high pressure grinding
For example, rock breaking in roller mills are typically based on compression, which is often seen as more energy efficient than impact breakage and is thus a more convenient choice for fine grinding processes (Lynch 2015). High-pressure grinding roll (HPGR) technology has gained increased acceptance by the mineral processing industry …

Trends in der Minenindustrie
Instead of conventional AG/SAG and ball mills, processes only with high-pressure grinding rolls (HPGR) and vertical mills (Fig. 5) or other combinations of mill types are employed in practice. Besides a pure grinding feed, a crucial aspect is the optimum energy utilization in beneficiation for the respective types of ore and applications.
