I'm trying to use this johnson 2.25hp dc motor to run a belt grinder. Is it possible to power and control it with a simple pwm box from Amazon. I found one with ac input and 6-90v dc output. I can't find an example of anyone with to this particular pairing.

Yes it has been done, but those controllers do not posses any kind of sophistication.
I assume you would not need variable speed apart from the ramp up to max for a grinder?
