How do I plane an installed slate countertop?

Built something cool? Need help bringing vision and reality into alignment? Let's talk about it here!
A belt sander with a medium grit paper, like 120 or 150 particles/cm2 may be the way forward for evening the slab out and then something really fine to finish it off with manually. I hadn't considered that. I too was worried about the angle grinder approach, it's a tool to be respected.
I would like to do that. But the slab is installed, and supports half of the kitchen sink. So no dice. I've just got to seal it off and use a vacuum cleaner at the same time.
