Industrial Vertical Stirred Mills Screw Liner Wear Profile ...

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.

Agitated media mills - Making

Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations.
