Figure 2 – Vertimill grinding and classification zones . Vertimills can be either top fed (the new feed is introduced into the top of the mill via a feed pipe that deposits the feed just above the grinding media), or bottom fed. In the case of Minas Rio, the cyclone underflow is fed by gravity into the bottom of the Vertimills.

1 Introduction. Ore deposits with high content of recoverables are becoming increasingly rare. For some ores, the decrease in metal content is so significant that grinding to particle sizes smaller than 80 micrometres (µm) and below is necessary to ensure sufficient liberation of the ore [1]. Fig. 1 shows an overview of the average copper content in the ore beneficiation plants worldwide ...

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.
