Stirred Media Detritors (SMD) - Outotec

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.

The Effects of Media Size and Amount on Grinding ...

In this paper,based on the establishment of laboratory model,we have studied the effects of media size and amount on the grinding efficiency of vertical stirred mill. The results indicate that smaller size media is conducive to improve the energy density and increase the specific surface area of grinding in the mill cylinder,while larger size media enhances the volume of grinding space and ...

Towards a Better Understanding of Stirred Milling ...

Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful application of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning
