Stirred Milling Technology – A New Concept in Fine Grinding
The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads The stirring effect is caused by rotating discs mounted on a shaft There are also stationary discs on the mill body positioned in between eachVertical stirred mills are grinding equipment applied for comminution, especially for fine grinding in regrinding applications where feed material is under 1mm The main parts of the equipment are the grinding chamber, internal liner, screw impeller, screw liner, motor engine, ball feeder, slurry feeder, and the discharge, as shown in Figure 1Industrial Vertical Stirred Mills Screw Liner Wear Profile In contrast, fluidized stirred mills use a rotational movement to fluidize a mediaslurry mixture, resulting in size reduction The type of mill and the circuit configuration are intrinsic to maximizing the grade and recovery profile of an ore Outotec offers both stirred milling technologies: Vertimill® is a vertical grinding mill using Stirred mills for wet grinding Outotec

Towards a Better Understanding of Stirred Milling
Stirred mill technology dates back to 1928 where the idea to use “an agitator and spherical grinding media” was presented The year 1948 saw the successful application of DuPont’s “sand mill” for pigment grinding Subsequent years have led to the development of different types of stirred mills spanningJan 01, 2016 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/sStirred Mills – Ultrafine Grinding ScienceDirectDec 05, 2014 The popularity of stirred media mills has risen in recent times CITIC HIC has developed our own range of vertical stirred media mills to complement our conventional grinding mills range, research and development team in Australia and CHina constantly working improving technology and efficiency of the machineVertical Stirred Mills (CITIC Stirred Mills CSM) CITIC
