Stirred Milling Technology – A New Concept in Fine Grinding
significantly increasing grinding efficiency. 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
Stirred Mill - an overview | ScienceDirect Topics
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.
Stirred Mills – Ultrafine Grinding - ScienceDirect
01-01-2016· These stirred mills are charged from the top or bottom and the product discharged either from the top end or from the bottom end after passing through a screen that separates the grinding medium from the ground particles. The screens may be flat or cylindrical so that they may be easily removed.

TECHNOLOGY SELECTION OF STIRRED MILLS FOR ENERGY,
Stirred mills are in general applied to fine and ultra-fine grinding applications. For the purposes of this paper, grinds of up to 75 µm are regarded as conventional, between 75 and 30 µm as regrind, below that and up to 10 µm as fine grinding, and finally below 10 µm as ultra-fine grinding.
Stirred Media Detritors (SMD) - Metso Outotec
Stirred Media Detritor (SMD) is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media and slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces that produce the desired grinding mechanism for fine grinding. Lower capital cost
