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-
Jun 01, 2020 Stirred media mills are used by the mining industry for ultrafine grinding to enhance liberation, and to decrease particle sizes of industrial minerals to tailor functional properties. This review describes stirred media mill technologies and operating principles, and summarises stress intensity theory which can be used for selecting efficient ...
While applications of stirred media mills for fine particle production have continued to grow, there is a lack of understanding of power requirements, optimum operating conditions and powder product characteristics underlying stirred media milling processes. To develop a physical understanding of stirred mill dynamics and scale-up principles, and to identify conditions and mechanisms for ...
The stirred media mill, which operates at about an order of magnitude higher power inteD.ity power per unit volume tban the tumbling mill, especially has attracted attention because of its reported bigh energy efficiency. ability for grinding into the mkron and sub-micron range and tedud ...
Outotec HIGmill is a stirred media grinding mill, in where the stirred effect is caused by rotating grinding rotors together with static counter rings. General structure is presented in Figure 2. Mill structure and operational description has been recently
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.
Jan 01, 2007 Stirred media mills belong to the group of mills with free movable grinding media , . Classical representative is the tumbling mill, consisting of a horizontally oriented rotating cylinder being filled with up to 40 by volume with grinding media. Owing to the rotation the grinding media are lifted and get potential energy which will be ...
Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations.
The VXPmill is a vertically oriented stirred media mill that is open to the atmosphere. They are designed with a modular impeller that has removable discs and spacers. Slurry enters at the bottom, travels upward through the mill chamber, and overflows through a media retention screen at the top.

In summary, the research has led to the development of a physical understanding of mill dynamics, performance and physico-chemical effects in stirred media mills. The scale-up principles established, the optimum operating conditions identified and the mechanisms revealed in the use of grinding aids have pointed the way towards more efficient energy utilization during fine grinding in stirred media mills.
