Stirred Milling Technology A New Concept in Fine
2019-5-8 STIRRED MILLING TECHNOLOGY Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in between each

Influence of slurry rheology on stirred media milling
2007-10-19 The wear percent is used as an evaluation parameter. In Fig. 14, the dimensionless wear rate for different types of grinding beads is plotted against specific energy consumption (kWh/t). It is shown that ZrO 2 beads have a lowest wear rate while the wear of SiO 2 beads is most serious and about 100 times as much as ZrO 2 beads.

2010-4-21 Beads formed by the fused process have the following disadvantages: During the production, it cannot be avoided that air bubbles are included in the beads; therefore the specific weight is reduced. Such air bubbles form pores in the inner structure of the bead—as can be seen in Figure 1 —and cause bead breakage during the milling process.
