    Models for understanding the basic concepts of fine grinding and how they apply to the design of stirred media mills have not yet matured. While spherical media in tower mills has previously been studied real grinding media shape in stirred mills can range from spherical (steel/ceramic balls) to highly non-spherical (sand or slag) resulting in very different media and grinding dynamics.

  • Stirred Milling TechnologyA New Concept in Fine Grinding

    Unlike tumbling mills where comminution occurs from both impact and attrition grinding in stirred media mills the particles suffer almost entirely attrition breakage between the beads. (Napier-Munn et al. 2005). In stirred mills there are no free-falling possibilities for grinding media meaning that impact action does not occur.

  • Stirred Media Detritors (SMD)

    Stirred Media Detritor (SMD) is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media and slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces that produce the desired grinding mechanism for fine grinding.

  • Development of an Energy Optimized Stirred Media Grinding Mill

    Jun 12 2014 · The article deals with an innovative approach of combining modern simulation techniques with pilot plant testing work with the target to develop a new stirred media grinding mill. With the help of discrete element simulation various mill configurations were studied. The target was maximizing the interactions between beads and the related power consumption. Small grinding media and thus small stress energies are required for an effective grinding i.e. for a minimization of the specific energy. Moreover the relations particularly the so-called stress model derived for grinding of coarser particles in stirred media mills are also valid for grinding of nanoparticles.
