Abstract. Fine grinding and dispersing, such as grinding in stirred media mills, gains importance in several industrial processes. Solid materials processing is frequently subjected to dynamic changes, effecting the performance of milling.

water-based ink. Experiments were conducted for fine grinding of organic rubine red pigment using a vertical bead mill. The experiments were conducted for varying sizes of grinding media from 0.5 mm to 1.0 mm, for two pigment loadings of 30 % and 37 %, and by extending milling time from 4 h to 6 h. The pigment particle size distribution

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 impact action does not occur.

Wet fine grinding is an important unit process in various industries. In the present work two different stirred media mills (one with a cylindrical stirrer; one with a disc stirrer) and a planetary ball mill are investigated using coupled CFD (computational fluid dynamics) and DEM (discrete element method) simulations.

IsaMill is a high-speed stirred mill that has been newly developed in the mineral industry for fine and ultrafine grinding. In this paper, a numerical model that is based on the discrete element method (DEM) was developed to study particle flow in a simplified IsaMill. The DEM model was validated by comparing the simulated results of the flow pattern, mixing pattern, and power …

The HIGmill is a stirred mill, which has a stationary shell, with a rotating shaft and mixing elements to agitate the small diameter ceramic media. The slurry enters the bottom of the grinding chamber containing grinding media (beads) and rotating discs which provide momentum to stir the charge against a series of stationary counter discs.

Fine grinding, i.e. comminution in the lower micrometer and sub-micrometer range, is thereby increasingly gaining importance, not only in the chemical and pharmaceutical industry, but also in mineral processing and ceramics industries. Stirred media mills are especially suited for wet ultra-fine grinding and dispersing.
