Stirred Milling VERTIMILL® Grinding Mills & Stirred Media

Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.

Stirred mills Metso

Stirred mills use less energy with grinding that results in decreased need for grinding media. The wasteful impact breakage of media-to-media or media-to-liner is eliminated, which ensures fewer fractures, and the media inside the mill can maintain its shape and usefulness longer.

Stirred Mills Ultrafine Grinding ScienceDirect

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.

IsaMill Wikipedia

The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
