Cellulose and starch nanoparticles were processed using a vertical stirred media mill used in previous works [11, 12]. The mill primarily consists of a rotating shaft having stirrer pins oriented in certain formation attached to a motor to rotate in a desired speed which can be controlled externally. This rotating shaft enters the milling ...

As fine grinding processes require mills with high energy densities as well as high production capacities, there is currently a great interest in research and development of dry operated stirred media mills. These mills are a promising option for energy efficient dry fine grinding especially due to their high stress energies and frequencies.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

The grinding media moves orderly in the vertically stirred media mill thereby resulting in more efficiency on grinding performance and much less power consumption. Since it is operated with wet grinding method, the vertical stirred mill does not require any cooling system due to the low speed operation.

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.
