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.
HPGR High Pressure Grinding Rolls. HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years.
The High pressure grinding roll has two opposite directions rotating rollers forming a nip between them, in which the ground material is drawn in and comminuted under high pressure becomes. The comminuted regrind leaves the nip in shape a so-called "Schülpe", which then desagglommeriert or needs to be unlocked. ...
However, rhenium oxide Re 2 O 7 has poor stability (sublimes at ~360 °C) and therefore is removed during the discharge. Rhenium has a high melting point and a low vapor pressure similar to tantalum and tungsten. Therefore, rhenium filaments exhibit a higher stability if the filament is operated not in vacuum, but in oxygen-containing atmosphere.
