Development of an Energy Optimized Stirred Media

2014-6-12  The stirred media mill principle is the setting into motion of grinding media by means of a rotating agitator, which transfers kinetic energy to the media. The feed material (either dry or as slurry) is dispersed within the grinding media and is stressed mostly by pressure and friction between layers of media.

Stirred Milling Technology – A New Concept in Fine

2019-5-8  In stirred media grinding, the energy intensity (kW/m³) is very high versus tumbling mills. In the HIGmill the power intensity (installed) is typically 180 to330 kW/m³. This means a very “packed” process: i.e., high throughput and/or high SGE in a small unit.

Is media shape important for grinding performance in ...

Models for understanding the basic concepts of fine grinding and how they apply to the design of stirred media mills have not yet matured. While spherical media in tower mills has previously been studied, real grinding media shape in stirred mills can range from spherical (steel/ceramic balls) to highly non-spherical (sand or slag) resulting in very different media and grinding dynamics.

2020-1-31  A stirred media mill works by reducing the product particle size inside a bed of grinding media. The grinding media consists of a granular mass of small bodies which are typically made of Limestone, steel or ceramic materials. The density of the grinding media usually varies between 2.0–7.8 g/cm3and their size is commonly between 0.1–10 mm.
