I am currently working on a home made grain mill. The rollers are 4 3/8" diameter & 6" long. I will be driving it with a 3/4 hp motor, but could up that to a 1 hp if need be. The drive sheaves that I can find at McMaster Carr will give me about 400 rpm. Does anybody have any idea if this will be too fast? I can slow it down a little more by substituting a 9 or 10 inch sheave for the 8" one that I'm looking at, but the price more than doubles at that point. How fast do you think these rollers will be able to go without running into problems?
