To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value 3.82 (round up to 4), and then divide by the tool diameter. For example, the ridiculously priced All Season 235/55R19 tires are a smidge over 29 inches in diameter, so that would mean (3.82 x 1320 SFM)/29.2 = 173 rpm.

Learn MoreThe torque speed characteristic of a typical ball mill is shown in Figure 1. On this curve there are three distinctive points of interest, which uniquely characterize the ball mill operation. Figure 1 a) The breakaway from rest is identified as the region on the graph

Learn Moreball mill specifications ball mill speed calculation. Calculations the critical speed of ball mill is given by, where r radius of ball mill r radius of ball for r mm and r mm, n c rpm but the mill is operated at a speed of rpm therefore, the mill is operated at x of critical speed

Learn MoreCalculations: The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.
