This was developed into the first 'stirred ball mill' by Klein and Szegvari in 1928 [20]. This prototype was refined into the Attritor mill, a low tip speed (3–5 m/s [21]) vertical pin mill which has been produced in various forms by Union Process since 1946 [19]. Several other stirred media mill designs have been developed over the ...

Some investigations demonstrate that stirred mills (compared to ball mills) have better performance when grinding occurs on a micron-scale . This improvement is because the mechanism of supplying energy during stirred milling is different from what happens in ball mills. In ball mills, the abrasive and impact stress lead to particle …

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 1.5:1. 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).
