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

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.Its also possible to note in figure 7 that k from vertical mill decreased along the year, even reaching smaller values than those for ball mills in some points. This is due the wear of cyclones apexes and, consequently, the increase on vertical mill circulating load, which reached values over 500% by the end of the year.Comparing ball and vertical mills performance: An
