Grain Mill - RPM

[SpottedDogBrewing]

Not sure if it matters but do RPM's make a different with grain crush when milling grain?
I have used a Ryobi cordless drill which I run at a lower RPM and a corded drill without any adjustment to the RPM's, just by depression of the trigger which is hard to regulate!!
Does it matter how fast or slow the crush happens?

I know a guy who swears that milling at high speed raises the temp of grain and does damage (never mind that he's about to stir it into 175 degree water,etc. Yes, he also mills his own flour) I like to crush at low speeds because it seems to leave more hulls intact, especially on a narrow gap setting.

MonsterMill recommends 175 RPM. I asked if 233 would be the same, he said, nah go with 175.

I know a guy who swears that milling at high speed raises the temp of grain and does damage . . .

Not so sure about the heat thing either, but higher speeds will shred the hulls making for poor lautering.

I agree with SankePankey. Stick with the manufactures recommendation or slower.

Barley Crusher say's 500 rpm, which seems a tad high. My DeWalt runs at 300 on the low setting, and has worked great for many batches.
