Tumbling mills - Minerallurgy

2021-7-2  A stirred mill is a stationary vertical or horizontal tubular shell that imparts motion to the charge by the movement of an internal stirrer (Napier-Munn et al., 1999). Tumbling mills are divided into four general groups: • Autogenous (AG) mills, where autogenous means self-generating, use only the ore in the mill as grinding media.

Stirred Milling Technology – A New Concept in Fine

2019-5-8  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.

Stirred Mills – Ultrafine Grinding - ScienceDirect

2016-1-1  Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.
