Conical ball mills are suitable for both coarse and fine grinding. Planetary Ball Mills: These mills consist of a rotating sun wheel and one or more grinding jars, which rotate around their own axis in the opposite direction of the sun wheel. Planetary ball mills are ideal for nano-scale grinding and mixing.

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.
