Stirred media mills in the mining industry: Material ...

Jun 01, 2020  Stirred media mills. Efficient grinding of fine and ultrafine particles requires small media to increase the surface area and the consequent collision frequency, but ball mills are fundamentally limited in the momentum that can be applied to such small beads by the force of gravity, which sets a practical lower limit in media size.

Mechanochemical modification of silica with poly(1‐vinyl‐2 ...

Mar 27, 2007  The polymerization of 1‐vinyl‐2‐pyrrolidone (VP) mechanochemically initiated by grinding silica was investigated in a wet stirred media mill. The polymerization itself proceeds from the silica grinding without any additional initiator. We have found that the amount of grafted polymer increases with an increase in total ground silica surface.
