Verticalrollermills (VRM) are an energyefficient alternative to conventional grinding technology. One reason is the dry inbed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here. Within these test works, mill parameters like grinding pressure, separator speed and dam ...

The effect and mechanism of magnetite concentrate morphology on the quality of indurated pellets were investigated. Concentrates with different morphologies were prepared using highpressure grinding rolls (HPGR) and ball mill (BM) grinding techniques. Then pelletizing and induration process is done in the temperature range of 800 to 1300 °C.

Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in the exploitation of magnetite iron ore deposits as an alternative to hematite DSO ores. Magnetite concentrate is a highergrade product than hematite and very desirable as a smelter feed.

Iron ores [1] are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite ( Fe. 3O. 4, % Fe), hematite ( Fe. 2O.

Highpressure grinding rolls reached great popularity for pressing iron ore concentrates since its first application in the 1990s. For this particular application, mathematical models describing HPGR performance on the basis of operating conditions and feed characteristics have successfully been used by the authors to map industrialscale operations under controlled conditions.
