What type of motor for a ball mill? Tools and Tooling Forum. 3lb mill would work but look at the 6lb also. A full load of lead media and chem charge in one drum and the 6lb mill will do just fine for small quantities. To be blunt: No, I will NEVER return to what I looked like, my face was burned off and replaced.

Optimizing the Ball Mill's RPM Make sure the whole roller assembly now looks as it originally did, and rotates freely. There you go: A larger, 3/4inch diameter drive roller, simple as that. Testrun the mill with a jar on it, and verify that the speed of the jar's rotation has increased to approximately 8090 RPM.

The optimum ball mill parameters to achieve a small particle size of µm include a ball mill speed of 500 rpm, a milling time of 10 h, and a balltopowder ratio (BPR) of 10:1. These settings are sufficient for obtaining better results. However, the study does have certain limitations that could be addressed in future research.

Figure 2 shows the XRD pattern of HCX1 ballmilled at 900/1100 rpm for 13 h. Analysis of Figure 2 shows that the XRD pattern has only the Mg phase and Ni phase without the production of Mg 2 Ni alloy. Compared with the XRD of the ball mill at 1600/1800 rpm for 9 h, the efficiency is lower. Therefore, the formation time of Mg 2 Ni alloy has a great relationship with the rotation speed.
