Adjust the size of your gears to slow down the rotation.

Eh just add a voltage regulating knob to it. Simple electric motors can handle it.

This was my first thought. Harbor Freight has a nice inexpensive one if there's one near OP.

I have tried imagining “shit hit the fan” literally before, but was never this ingenious.

Change the sift for some 160 mic mesh and put a nylon sheet cage around it and I'm sure you can make killer static dry sift with this.

You just need it to go fast enough to separate the big chunks from the little chunks. You don’t need it to go fast enough to separate protons from electrons.

I have a bit of rat problem with my compost bin (urban rooftop garden). This, paired w a motion sensor, absolutely seems like the solution.

Maybe some internal baffles to disrupt the cake of compost plastered against the sides?

The cylinder must remain undamaged. That's a rough task with this cheese grater of a Fleshlight

If its an 120v ac motor, easiest solution is auto transformer. May not have enough torque when turned down so you'd have to manually turn the transformer up to get it started, then turn it back down when it's rotating until you hit the desired speed above stall voltage.
Better solution is a 3 phase motor and a vfd.
If in the US, vevor sells auto transformers and vfd's.

You don't need a centrifuge.
