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 machine.
Vertical agitated wet media mill. Agitated media mills are media mills that employ an agitated (or stirred) grinding media action for grinding of the ultrafine particles. In this case, a ceramic grinding media grinds mineral, metal, or chemical powder. The most typical application is the manufacture of GCC slurries used for the production of ...
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 …
JM series vertical stirred ball mills is a kind of high efficiency ultrafine ore grinding equipment (also called tower mill or vertical spiral stirred ball mill), mainly adopted for the ultrafine grinding test research, also for the small scale industry grinding production, to provide reliable technical parameters for industrial production.
Vertical wet stirring mill equipment is mainly divided into mixing mill (tower mill) and sand mill. The barrel of the stirring mill is thicker and the spindle angular velocity is lower. The grinding medium can be either a sphere or cylinder with a diameter of 4-12mm, or a microbead with a diameter of 0.2-3.0mm. The angular speed of the main shaft of the sand mill is relatively …

Using a too big mill running at a low charge level is thus not recommendable. The mills can be operated both wet and dry, continuous or batch-wise. For continuous wet grinding feed pulp is pumped or gravity fed at the bottom of the mill and overflowing at the top. See fig.1. As me dia have been used stell balls or cylpebs from three to tvelve mm
Vertical Stirred Ball Mill The wet grinding tests were carried out in a vertical stirred ball mill with polyethylene liner inside which had a diameter of 150 mm and a height of 170 mm (Figure 2). The stirrer axis is fitted with four slotted shaft and arms (stainless- steel). The shaft is rotated with a motor which has ...
Wet grinding with vertical stirred ball mills is typically carried out for slurries containing particles smaller than 200 μm, such as industrial minerals and pigments. Filtration is an important unit operation, which is performed in order to reduce the water content of the slurry after grinding and concentration, and prior to drying and ...

Drug nanocrystals have been used for a wide range of drug delivery platforms in the pharmaceutical industry, especially for bioavailability enhancement of poorly water-soluble drugs. Wet stirred media milling (WSMM) is the most widely used process for producing dense, stable suspensions of drug nanoparticles, also referred to as nanosuspensions. Despite a plethora of …
Modeling of wet stirred media mill processes is challenging since it requires the simultaneous modeling of the complex multiphysics in the interactions between grinding media, the moving internal agitator elements, and the grinding fluid. In the present study, a multiphysics model of an HIG5 pilot vertical stirred media mill with a nominal power of 7.5 kW is developed.
Wet Grinding. NETZSCH-Feinmahltechnik GmbH is one of the market leader in wet grinding technology. The bundling of process-related know-how and the extensive machine program from laboratory to production machines to complete production lines is our strength. Agitator bead mills are grinding machines for ultra-fine processing of solids in liquids.

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 mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented (Stehr, 1988). The year 1948 saw the successful application of Du Pont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of
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.
