small 1"ish pulley on the motor, large 10"ish pulley on the grain mill to lower the rpms.
There are a bunch of threads on motorizing grain mills that will help you out.
I'm actually motorizing my monster mill mm2.0 tomorrow. I'm using a 3/4 hp motor from a garage door opener. I got a 1.5" pulley and a 12" pulley with a 45" 3L v-belt from grainger.com

I have completed a very similar project ... https://www.homebrewtalk.com/f51/motorized-grain-mills-time-show-them-off-159950/index17.html
I used a 2" on the motor and 7" on the mill. This should give about 550-600 from a 1725 motor.
(WOW, I thought my 1/2h farm duty was overkill, 3/4? Look out grain!)

perfect motor. Reversible isn't something you'd use. Just get a good set of sheaves or a gear reducer. You getting a good price for it?

Nice! Go with the 1.5" on the motor and 12" sheave on the mill. 3/4 hp will be more than enough power. I use a 1/4 hp on mine. I usually start it up then add the grain but a couple times I've loaded the grain then started the motor. So far it hasn't even hiccuped on me, so you'll shouldn't have any worries with a 3/4hp motor.
