As far as placement of your mill, the ideal distance is probably around 150ft or more away from any buildings of any sort. If you can barricade it that's even better (things like sandbags). Just make sure you don't block off air to the motor. When making black powder there is always a chance for it to go off.

The powder (g) to media (g) ratio was maintained at 1:30 for all milling experiments. This ratio was based on some initial trials conducted with different ratios. To improve the dry milling method, 25% water on the weight of fibre snippets was added at the start of milling. In wet milling, 1:10–15 powder (g) to water (mL) ratio was used.
