Research of iron ore grinding in a vertical-roller-mill
For the grinding tests, a Loesche mill LM4.5 (table diameter 0.45 m) is used (Fig. 2a). This pilot scale mill is a special development for ore grinding, which is reflected by several features. The mill has four rollers, which are able to stress the particle bed with grinding pressures of up to 5000 kN/m 2. Various different roller geometries ...
