Don't think there would be an ethical problem with that; it's instantaneous and probably less prone to error than injections. But the optics aren't quite as good.
I don't think it's instantaneous, though it would be fast. Whirring metal blades can only spin so fast, and a human-size grinder would be much larger than a chick-sized one, so it wouldn't be able to spin as fast. Also, assuming you drop the human into the blades feet-first, just using normal gravity, there's going to be some amount of time between the feet getting ground up and the head. Whether this is perceptible to the doomed, I guess would require some calculations involving nerve conduction speed.

The grinding is extremely fast - too fast for the chick to experience pain before it's dead.
There are far far far more important animal welfare issues to worry about.
But it doesn’t seem like we’re worrying about those all that much…
Maybe we should build a scaled-up version for human executions.
