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

Today, closed­ type stirred media mills are built with grinding chamber volumes of less than 1 litre (laboratory 92 Fig. 2 Design principle of a closed-type stirred media mill with disc stirrer scale) up to more than 1 m3 and with drive powers of more than 1 MW [2].

Measurement of the motion of grinding media in a

2004-11-1  The motion plots for the mixed media depict that the media stratifies within the mill when in operation. This effect has not been reported in any known, previous investigations. This has important implications to the motion in the stirred mill. In any sample of grinding beads there will be differences in the size of the media.
