Of Hpgr Mills In Iron Ore Processing


  • HPGR vs SAG - Metallurgist & Mineral Processing Engineer

    HPGR will be the better performer when you have a very consistent ore body as that machine can be specifically set up to maximize the greater ore quantities. It is when the ore body feed to processing has a wide range of ore variations that fast processing adjustment and flexibility is demanded. Then SAG takes the lead.

    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.
