Jan 01, 2016· 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.
Jun 01, 2020· This was developed into the first ''stirred ball mill'' by Klein and Szegvari in 1928 . This prototype was refined into the Attritor mill, a low tip speed (3–5 m/s ) vertical pin mill which has been produced in various forms by Union Process since 1946 . Several other stirred media mill designs have been developed over the subsequent ...

al., 2005). In stirred mills there are no freefalling 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.

Sep 01, 2008· It was suggested to use a continuous stirred tank reactor (CSTR) located between a ball mill and a hollowfiber cartridge, in order to decrease the energy costs . Another disadvantage of milling is its inability to remove the lignin which restricts the access of the enzymes to cellulose and inhibit cellulases [ 30, 68 ].

The energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the tumbling ball mill. Although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill, it became less so as grinding proceeded and for a product median size of microns it was the same.
Gravityinduced stirred mills initiate a ball charge motion via rotational movement of a screw to provide a size reduction mechanism. In contrast, fluidized stirred mills use a rotational movement to fluidize a mediaslurry mixture, resulting in size reduction. The type of mill and the circuit configuration are intrinsic to maximizing the grade ...
