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 wet milling process in stirred media mills is applied by various industries for the production of fine particles, for example, pharmaceutics, inks or ceramics .The minerals industry has also adopted horizontal stirred media mills , such as the IsaMill TM, to meet the demand for particles in the lower micrometer range .The production of nanoparticles is possible using
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

Grinding and dispersing in stirred media mills is a process which is widely used in different industries such as chemical ceramic pharmaceutical filler ink and cosmetic industry While usually stirred media mills are employed to produce products in the micro and
Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations.

The patented IsaMill is a transformation in grinding technology based on high intensity stirred milling. The IsaMill was developed for fine grained orebodies that needed a step change in processing efficiency to be economic. The IsaMill significantly reduces the energy requirement, and media and capital costs of fine grinding.
