IsaMill - Wikipedia
Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill. The mixing chamber is filled with the grinding medium (normally sand, smelter slag, or ceramic or steel beads) and a suspension of water and ore particles, referred to in the minerals industry as a slurry. In contrast, ball mills, rod ...
Stirred Milling Technology – A New Concept in Fine Grinding
al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 µm.
