Stirred media mill (SMM) is a useful tool for particle engineering tasks.Advantages of SMM: amorphization, shape control, solid-state reactions.Stirred media mill has higher energy intensity and energy efficiency than other HEM.Properties of products can be controlled by optimize the grinding circumstances of SMM.

Comminution in stirred media mills is a frequently applied top-down method towards the production of micron- and submicron particles. However, due to the high energy density, this type of mill is appropriate for mechanical activation (MA) as well. Despite the vast field of mechanochemistry which encompasses an increase in reactivity by mechanical energy input, there is only limited publication on stirred media mill-based MA until now. The main focus of this paper is the short introduction of MA and review of the above field related to the mentioned mill type. It can be identified as a general conclusion that this recently introduced mill is not yet applied in a wide range in MA compared to other high energy density mills (HEM) like planetary ball mill or vibratory mill which have been used since long time. However, the results published on the mechanical activation in stirred media mill seems very promising which is forecasted the increase of publication in number in the future. The basis for this lies in its high energy density (310 times higher than other HEM), the ability of continuous operation, high number of operating parameters (circumferential velocity, ball size, material, wet or dry state, drying in the mill, ) makes it a well controllable method for the manufacture of high value added products such as advanced materials or various composites.
