HPGR High Pressure Grinding Rolls Weir

Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid volume, exceeding its ...

Thorium Energy Viability - Stanford University

Thorium would make uranium-232 in reactors when being irradiated, which emits dangerous levels of gamma rays. [9] The thorium-uraninium cycle produces uranium-232, which decays to Tl-208, which has a 2.6 MeV gamma ray decay mode. This process is therefore require higher costs since it needs more expensive fuel handling and reprocessing since ...
