Vertimill ® The Vertimill® is a vertical stirred mill that uses a helical screw to impart motion in the charge. Mechanically, the Vertimill is a very simple machine with an agitating screw suspended into the grinding chamber, supported by spherical roller bearings, and driven by a fixed speed motor through a planetary gearbox.

This was developed into the first 'stirred ball mill' by Klein and Szegvari in 1928 [20]. This prototype was refined into the Attritor mill, a low tip speed (35 m/s [21]) vertical pin mill which has been produced in various forms by Union Process since 1946 [19]. Several other stirred media mill designs have been developed over the ...

stirred mills will vary from sitetosite and from milltomill. Optimization of a given stirred mill with respect to specific energy input depends on the complex relationships between a large set of parameters. Examples include mill speed, media size, media loading, slurry density, slurry flow rate, slurry rheology, feed material characteristics.

In the 1950s and 1960s ball mills dominated primary grinding, however they were supplanted in the 1970s by AG and SAG mill which also replaced two stages of crushing. Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills .
