Critical Speed Of The Ball Mill Nc In Powder Metallurgy

 · The milling time was set to 200 minutes, and cycles of 2 minutes ON and 9 minutes OFF were chosen to reduce frictional overheating. The ball to powder ratio (BPR) was set to 10: (g/g) using spheres in 100Cr6 steel with a diameter of 10 mm.

Figure 12. Typical carbonylmetal powder A) Nickel; B) Iron f10 Powder Metallurgy and Sintered Materials TiC, NbC and TaC are produced by direct reduction and carburization from their oxides (TiO2, Ta2O5, Nb2O3) in vacuum at 1700–2300°C. The reaction products are milled to powder in ball mills .

 · The mill was rotated at 63% of the critical speed. The position of the balls at the end of five revolutions is shown in Figure 2. It is seen that, using a low coefficient of friction at the walls, balls tend to flow down the surface of the charge, and a "toe" begins to form. As the friction at the wall increases, aracting motion is observed.
