Stirred mills - for wet grinding - Outotec
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.

Media stress intensity analysis for vertical stirred mills
2001-10-1 Stress imposed on particles is result of the centrifugaI forces of grinding media being agitated at high speed. In this situation stress intensity is proportional to the cub of media size, stirrer speed velocity squared and the difference between the media and slurry density (Kwade, 1996). In low speed vertical stirred mills (LSV) such as the ...

Stirred Mills – Ultrafine Grinding - ScienceDirect
2016-1-1 Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. The stirred mills are charged with a media size of 10–12 mm and operated at a maximum tip speed of 3–8 m/s.

A Novel Particle-Based Approach for Modeling a Wet
2021-1-9 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.
