Planetary Ball Mill PM 100 Wet and nano-scale grinding with the PM 100. Wet grinding is used to obtain particle sizes below 5 µm, as small particles tend to get charged on their surfaces and agglomerate, which makes further grinding in dry mode difficult. By adding a liquid or dispersant the particles can be kept separated.
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.
