For me they work fine, even as a manual solution.
You probably need just as good a drill for a more expensive mill would you not?

Heres my stab at this...
The cheaper one is a Mill.
The expensive one is a Crusher/Roller.

Mill:
There is higher resistance/friction as the crushed grain stays briefly in the mill area with the unmilled grain. The surface area of the contact patch also comes into play. Off the top of my head, say r1=100mm diam plate, r2=20mm centrepin, ((r1*r1)-(r2*r2))*22/7=7543mm2.

Crusher/Roller:
This crushes the grain through a set gap so once crushed, the grain is no longer in play. For, say, l=100mm rollers, say r=10mm, the contact area is only going to be roughly 500mm2.

Blunt has a Crusher/Roller, runs it off a drill and is very happy with it.

Maybe I'm missing something but most cheap appliances have a designed duty cycle . . . run 1 min, cool 2 mins or whatever. So:
- run a couple of kilos through the mill with a cheap drill,
- let the drill cool down (have a beer, fire up the boiler),
- run another couple of kilos through the mill with the cheap drill,
- let the drill cool down (have a beer, sterilize something),
- run another couple of kilos through the mill with the cheap drill,
- let the drill cool down,
- plug the hand attachment back in and get some exercise (if, like me you have zero time for gym, any excuse to go manual is seen as an opportunity).

Btw, prior to that last post, I had just came in after lying on my back in a field in Galway with my 13 year old boy going "wow" as the meteor storm began on a clear night (better tomorrow, but forecast is all cloud so prob no wow).

As a single parent . . . . pure magic.

Wow.

Anybody else see that?
