How do you get “powder?” Can you add more lye if there’s been naptha?

How do you get powder from a blender? I have chipped bark. I’ve blended the hell out of it, broke the blender I did so much. It comes to a point where it just doesn’t grind finer. There’s some dust, but most is tiny strands left over, not powder.

Can you add more lye after you’ve done an extraction? You know, there may be naptha left in there somewhere. Would that cause an emulsion or other issues when you added naptha again to extract?

These simple coffee grinders will make short work of MHRB, usually you can find them at the second hand store for 3€ or so and they are usually good for quite some time.

Something like this with the spinning knife inside.
