The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...

There is a large gap between the tip speed and power intensity of the lowspeed vertical mills and the highspeed horizontal mills. The VXP mill bridges the gap between highspeed and lowspeed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.

The milling circuit is preceded by two parallel roll crushers in closed circuit with five millimeter single deck vibrating screens. The ore then passes into a twostage grinding circuit, consisting of two parallel primary ball mills and two parallel secondary ball mills, as shown in Figure 1. The target grind size for this circuit is 75 µm.
