Jun 26, 2019· In the test,moisturecontent of ores had two kinds, the lowest 3.8% and highest 11%. It took 60kg ores for this test. And 20kg was ores with 3.8%moisturecontent and 40kg was withmoisturecontent 11%. Particles processed byHPGRare classified according to their size to see the result of grinding. （4）Test purpose

Dec 01, 2009· The energy saving of thismillis claimed to be similar to that ofHPGRand 30–50% lower than a ballmill(Cordonnier, 1994). In raw material grinding up to 20%moisturecontent, 50% energy reduction (Marchal, 1995) and savings in capital costs of between 12% and 15% could be achieved compared to ballmills(Buzzi, 1997).

TheHPGRis often a quaternary crushing device which is the reason that the footprint for anHPGRplant is so large. To place a ballmillor a VERTIMILL directly on theHPGRproduct may work on soft iron ores but will not work well on harder ores that require over about 7 kWh/t to achieve a T80 of 1.7 mm.

(3) Therollerpart is the hardcore part of the crusher. The connection betweenmill rollerand main shaft adopts key and taper sleeve, which is dismounting easily. (4) The gap between two rollers can be read from staff. The place where there is a hole under the staff is the zero reference line. The gap is 10 mm when the machine leaves the factory.

HPGRor 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. After these developments, anHPGRbased circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. …

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 anotherrollerthat is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
