Abstract The high pressure grinding rolls HPGR is a relatively new technology which offers the potenetial benefits in energy savings circuit simplicity and improved product characteristics in
The results showed that the HPGR ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG ball mill circuit at the same P80 grind size of 160 mircons μm At a grind of 80% passing 75 μm the HPGR stirred mill circuit showed a 34% reduction in energy compared to the base case
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
