Stirred mills - for wet grinding - Outotec
The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines. Vertimill® energy savings can range from 30% to greater than 50% compared with traditional mills, and the SMD energy savings can be far greater than 50% of ball mill energy in fine grinds.

Figure 1. Schematic representation of the crushing mechanism in a ball mill In wet grinding, the surrounding medium is liquid, as opposed to dry grinding. Wet grinding should be considered in cases where the material is prone to static charging, or when the material is toxic and dust containment is difficult.
