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.
Silicon Carbide Balls. Silicon Carbide Balls are very high-cost grinding media that are used for milling same materials (silicon carbide ball to mill silicon carbide materials) to avoid contamination. They are only available in 5mm,10mm, 15mm and 20mm sizes. They are a special order item. Specific Gravity: 3.1; Hardness: KNOOP 2500 kg/mm 2
Ball milling was carried out using a Fritsch Pulverisette 5 planetary ball mill with tungsten carbide lined grinding vials and 10 mm diameter WC balls with a ball-to-powder weight ratio (BPR) of 10:1 for 20 hours of duration. The milling operation was carried out in a toluene medium with a constant rotation speed of 300 rev/min.
