Does anybody know the proper RPM's for a grain mill?

I have a Valley Mill which I understand production stopped several years ago.

I saw a posting asking how to remove the hand crank and convert to a drill or motor. I will put a photo on Facebook (Black Hills Homebrew Supply). Converting from the hand crank to a drill requires the purchase of two common items at a hardware store. A shoulder bolt that accepts an allen wrench and a matching hex adapter for the drill.
 
I was about 300 with pulleys and had a good crush, but would slip the pulleys once and a while especially if I overconditioned teh malt.

I've got a gearmotor now and it runs about 160 rpm IIRC.

I like the gearmotor best, but could use a bit more speed to make crushing a bit quicker, but I'd also need a larger Hp motor to make that happen. I wouldn't bother with the drill and just search for a cheap motor and pulleys or gearmotor and couplers.
