### Critical rotation speed for ball-milling ScienceDirect

To examine the dependence of critical rotation speed on ball-containing fraction, we measured critical speeds at various ball-containing fractions from 0.3 to 0.95 stepped by 0.05. Since at lower fraction than 0.3 we could not observe the centrifugal motion, we chose this fraction range.To examine the dependence of critical rotation speed on ball-containing fraction, we measured critical speeds at various ball-containing fractions from 0.3 to 0.95 stepped by 0.05.

The rotational direction of a pot in a planetary ball mill and its speed ratio against revolution of a disk were studied in terms of their effects on the specific impact energy of balls calculated from the simulation on the basis of the Discrete Element Method (DEM) and structural change of talc during milling.The optimum rotational speed is usually set at 65–80% of the critical speed. These data are approximate and may not be valid for metal particles that tend to agglomerate by welding. The minimal magnitude of ball size is calculated in millimeters from the equation:Ball Mill an overview ScienceDirect Topics

However, reports on the efficient combinations of ball size—rotation speed have been sparse in the literature. Here we report that there exists an optimal ball size for efficient milling at a given rotation speed, based on a laboratory-scale wet ball mill.The mass of the ball mill, its size (diameter), and milling/rotational speed have been reported to be essential factors that influence the MA process where the rotational speed predominantly supersedes the other two parameters because the appropriateness of the milling apparatus’s impact energy is a function of the sufficient Theoretical Modeling and Experimental Evaluation of
