The first example was a "stirred ball mill" prototype developed by Klein and Szegvari in 1928 [6]. In 1946, this evolved into the modernday "Attritor mill", a vertically operated pin mill that could grind particles even at low tip speeds. Since then, several variations have been manufactured using this design template [7].

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
