2018626 The appendix of the paper lists the mill speed as 12.5 RPM. The mill is fixed speed so the critical speed is only a function of mill effective diameter as liners wear. Doing the math neglecting the balls gives a 68.4 critical speed. The ball mill belly length can be achieved with a 18 degree head angle and 1.9 m trunnion diameter.
