Another milling method, attrition mills, has been replaced by the large tumbler ball milling to achieve large-scale production of commercial alloys. Another type of mill, the vibratory tube mill, has been used for pilot-size production [4]. The motion of the balls and particles in a vibratory mill was complicated.
The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
