Stirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products. SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product. They are suitable for both open- and closed-circuit operation.

Wet comminution in stirred media mills is a frequently applied fully scalable top-down method towards the production of micron- and submicron particles. Despite the vast field of mechanochemistry which encompasses an increase in reactivity due to the effect of mechanical energy input, there is still no clear picture of the involved mechanisms.

Nanoparticles can be produced by wet grinding in stirred‐media mills. In the lower nanometer range a true grinding limit exists, where the transferred energy from the grinding media is no longer sufficient to induce further breakage of the particles even after stressing events with high stress energies.

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.

Stirred media mills, also referred to as stirred ball or stirred bead mills, generally have a good ability to produce fine particles with a relatively narrow particle size distribution. Wet grinding with vertical stirred ball mills is typically carried out for slurries containing particles smaller than 200 μm, such as industrial minerals and pigments.

The importance of stirred media mills in various industries and in research is steadily increasing. The comminution process in these mills is determined mainly by the number of stress events in the grinding chamber and by the intensity acting at these stress events: for a certain stress intensity a certain relation between the product fineness and the number of …

Wet stirred media milling (WSMM) is the most widely used process for producing dense, stable suspensions of drug nanoparticles, also referred to as nanosuspensions. Despite a plethora of review papers on the production and applications of drug nanosuspensions, modeling of WSMM has not been thoroughly covered in any review paper before.

significantly increasing grinding efficiency. 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

As stirred media mills are operated usually wet, the chapter focuses on wet grinding. Grinding and dispersing in stirred media mills is a process, which is widely used in different industries such as chemical, ceramic, pharmaceutical, filler, ink and cosmetic industry. Stirred media mills belong to the group of mills with free movable grinding ...

The present paper deals with the differences and similarities of the wet and dry grinding in stirred media mill from energetic and mechanochemical point of view as well.

Modeling of wet stirred media mill processes is challenging since it requires the simultaneous modeling of the complex multiphysics in the interactions between grinding media, the moving internal agitator elements, and the grinding fluid. In the present study, a multiphysics model of an HIG5 pilot vertical stirred media mill with a nominal power of 7.5 kW is developed.

In general the possibility to produce nano-particles by wet grinding in stirred media mills could be shown recently (Mende et al. 2003, Mende et al. 2004, Stenger et al. 2005).
