Thank you for your reply.
These people have a explainer on calculating the appropriate speed for a belt grinder belt: https://www.redlabelabrasives.com/bl...a-belt-grinder
I suspect 5500 RPM is quite a bit too high for direct drive, you might need to add a speed reducing pulley set between the motor and belt driving wheels to bring it down in speed.
Thank you very much

I use 4,000 FPM +/- 1,000 FPM depending on variables (i.e., material, grit, abrasive binder, etc). Equally important is 1 hp per inch of belt width. (i.e., 2" belt width = 2 hp). That is a professional value and you will never be disappointed. You will see lower horsepower numbers but you certainly don't hear the disappointment with all the 1/2 hp systems out there. 50 years ago the owner of Burr King (manufacturer of Industrial grinders) gave me that horsepower parameter and he was right!
I agree, 5500 RPM and potential wheel diameter will verge on astronomical FPM, versus reduction available attached to the motor. I can't read French, but if there is sufficient power, a variable ratio is a good option for a sander/grinder.Quote:

It seems like you have a good motor to start with. If you add a VFD, to dial in variable rpm, you will have a good solution for most materials. I have the chart below posted next to my machine. (FPM x .3048 = MPM)
