Shredding belts

[steve31]

I'm having a problem with my belts being shredded at high rpm. The pulleys have some pitting in them from rust and I assume this is my problem. My question is, can I get away with sandblasting the pulleys or should they be replaced? Any other ideas? Trying to do this cheap, but will bite the bullet if needed. Thanks.

Getting the rust off usually helps.Sandblasting and fresh paint can't hurt.
I took mine off and used the wire brush on my bench grinder..belts run fine now.

I usually stick rusty pulleys on big bolt clamped in a vise. Then use a 4" angle grinder with a 120grit disc on it and let the pulley spin while sanding it. This gets rid of the rust pits and makes it smooth again and even. I also use a leather glove and keep the pulley spinning at a lot slower speed.
Then when painted and allowing the paint to dry for a couple of days, the pulleys act just like new ones.
