Research of iron ore grinding in a vertical-roller-mill
Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.

Mining and Processing Iron Ore Vulcan® Drying Systems
Iron ore needs to be dried prior to processing. Drying reduces shipping and storage costs, making the material easier to manage.Pre- drying iro n ore helps improve pro cessing times, reducing energy co nsumption at stee l mills. Drying also helps eliminate ste am that is gener ated, making the ore safer to transport.

of these four materials in dry and wet grinding conditions. It shows that coal and dolomite are easy to grind materials by dry grinding method whereas iron and manganese ores are suitable for wet grinding. It was seen that wet grinding improve the material fineness than dry grinding and maximum 15% improvement in D 80 was seen for iron ore samples.
