determine ball mill rpm formula

2011/4/2I can help in inches.. rpm = cutting speed x 4 divided by cutter dia. cutting speeds roughly alloy steel = 50 feet per minute, cast iron, 70 mild steel 80 to 100 and brass and aluminum, 200 these are for hss tools. If you talk limey its aluminium. In the lathe dia is the Output RPM formula = Input RPM times number of driving gear teeth divided by number of driven gear teeth. A small transmission in a mixer has a 12-tooth gear on the motor shaft driving a 72-tooth gear on the mixer blade. The motor is turning at 1,800 RPM. What

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.

For instance, a 90cm diameter ball mill has a critical speed of 44 rpm. you need now to determine the optimal speed which is about 70-75% of the critical speed. More detailed Critical Speed Of Ball Mill Formula DerivationBall mill critical speed derivation .
