Compared to ball mills, stirred mills are more energyefficient, even at a moderately coarse P 80 of up to 100 μm . When the agitator speed or mill power is kept constant, the specific breaking rate decreases as the proportion of particles in the media rises. Regarding the size distribution, particle breakage rate, and product size, there is ...

IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of :1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).

A dry operated, horizontal stirred media mill was used for the fine grinding of limestone and compared in open and closed circuit modes. It was found that the choice of grinding aids as well as the stirrer tip speed are crucial for the mill operation, especially in terms of the grinding efficiency and the transport behavior through the mill.

Figure 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.

Brissett (2010) reviews several industrial cases of stirred milling against ball milling. Vertical mills can operate at higher volumetric load (6085%v/v) than ball mills (3545%v/v), which then leads to higher productive throughput capacity (tph/m3). Fig 2 shows that that savings for a vertical mill can range from
