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.
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.
Stirred media mills are relatively new to mining industry, and several new technologies have been developed such as the VXPmill (vertical stirred mill). There is little technical understanding of optimizing and scaling-up of the VXPmill. This thesis addresses both of these issues and therefore supports commercial applications of this vertical stirred mill. Stirred media mills …

The vertical stirred mill showed energy savings of 25%, 37%, and 27% relative to a ball mill in coarse grinding duty. For desired particle sizes less than 40 microns, horizontal stirred mills show increasing advantages over ball mills.
Its also possible to note in figure 7 that k from vertical mill decreased along the year, even reaching smaller values than those for ball mills in some points. This is due the wear of cyclones apexes and, consequently, the increase on vertical mill circulating load, which reached values over 500% by the end of the year.

There are many different technologies that can be used for regrinding applications, such as ball mills, and high intensity stirred mills. Among the alternatives, the vertical stirred mill (Vertimill by ) has become a popular option for fine grinding the minerals industry. This isin due to a good balance between cost and energy efficiency.

I see that several have answered based on dry grinding, i.e. Vertical Roller Mill vs. conventional Ball Mill. If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies.
circumstances stirred milling is significantly more efficient than ball milling. As a case in point, the VERTIMILL® grinding mill has been cited in a couple of papers (Nesset et al., 2006; Mazzinghy et al., 2012) as being some 35% to 40% more efficient than ball mills for fine

The economical CL Attritor Stirred Vertical Ball Mill is used for wet grinding limestone for flue gas desulphurization. The process uses limestone feed stock of approximately 6mm in size and wet grinds the limestone to 95% minus 325 mesh. The CL …
Vertical mills are generally cylindrical in shape and stand on their ends with a stirrer suspended from the top end of the cylinder. One exception is the Stirred Media Detritor Mill which is octagonal in shape. In all these mills the stirrer is located centrally forming the long axis of the shell.
The stirred ball mill has been found to be more energy efficient than the tumbling ball mill. An energy reduction of 50% was possible for a product size of 6 microns when the stirred ball mill was employed instead of the tumbling ball mill. The energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the ...
