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 material to the desired smaller grain size.

The lateral pressure also produces an axial thrust component in the wall of the pipe where the maximum moment occurs, which is typically at the pipe invert. Similar to arches, the effect of axial force in a pipe wall is significant in design. Arch structures made of concrete rely on this axial compression for their load carrying capacity.
