Why HPGRs are revolutionising mill circuits

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 energy-efficient grinding machines are mostly used for processing iron, gold, copper and diamond ores, although they’re
