ball mill operating rpm calculation

The rotation of planetaryball millequipment varied from 200rpmto 350rpmand the charge ratio varied from 20:1 to 35:1. The diameter of steel balls was 19.6 mm. It can be seen from the Fig. 4 that the reaction rate constant is linear with the effective collision power (P e ) as a whole

Effect ofMillSpeed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. Themillwas rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the
