Its a real simple recipe: 75% Pot. Nitrate, 10% Sulphur, 15% Charcoal, tumble for about 3 hours, dampen and form into a ball or compress into a puck. When dry, granulate using screening.
I watched a video showing Swiss making their powder. I wish I could find it again. It was 10 years ago. They use really old equipment, but it's obvious they put a lot of time into making their powder. Way more steps than you describe and much more time.
