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 ...
