Concrete Mineral Iron Ore Grinding Ball Mill
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.
