torque speed calculation for ball mill

How to Determine Cutting Speeds for Machining Tools - dummies

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.

Ball Mill Operating Speed - Mechanical Operations Solved

Calculations: 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.
