Research of iron ore grinding in a vertical-roller-mill

2015-3-15  The application of vertical-roller-mills (VRM’s) for ore grinding is part of the second strategy. The grinding parts of a Loesche mill ( Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system.

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. Within these test works, mill parameters like grinding pressure, separator speed and dam

anyone done surface grinding on a vertical mill

2018-5-24  Grit is a slideway's enemy. Buy a used surface grinder for $700 and use that. If you insist on exploring this learning curve, use a depressed center stone re-enforced grinding disc. Spinning an AO rock on there will blow up if you make one wrong move with the feeds. And God save your mill.
