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.
