Wet comminution in stirred media mills — research and its

Nov 01, 1999· The importance of stirred media mills in various industries and in research is steadily increasing. The comminution process in these mills is determined mainly by the number of stress events in the grinding chamber and by the intensity acting at these stress events: for a certain stress intensity a certain relation between the product fineness and the number of stress events exists.

Stirred Milling Technology A New Concept in Fine Grinding

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.

Representative On-line Measurement of Comminution Results

The engine of the mill has a driving power of 3.3 kW. In order to reduce the amount of wear from the materials of the mill the grinding chamber was lined with ceramic walls (SiSiC) and the stirrer was supplied with 5 perforated discs of polyurethane (PU). The experimental set-up provides a circuit mode comminution of the product (s. Figure 1).

COMMINUTION Comminution conundrum

When fine grinding in a tumbling mill, the production of unwanted noise and heat wastes valuable energy. A stirred media mill, like the Vertimill or SMD, is an energy-efficient alternative to a tumbling type mill for fine Outokumpu Technology’s SAG mill at Sally Malay, Australia.
