Collector RPM

[Andrew Rudolph]

We just put up a cad walk through of our intake roller system, it was running around 200 rpm.

Use your inner engineer and experiment yourself

You'll have more fun (maybe a few more headaches) that way

A typical rule of thumb is to gear your intakes for a little bit higher of a surface speed than what your drivetrain is geared for. For example if you have geared your drivetrain for 10ft/s, aim for 11-12ft/s surface speed of your rollers. If you can't do the math yourself JVN's mechanical design calculator has an intake section that's really useful.

There's a logical reason for this rule of thumb. OP, take a guess?

Hint: it was explained in one of the videos.
