My modified ball mill using brass balls - Pyrotechnics ...
My modified ball mill using brass balls - posted in Pyrotechnics: Hello forum. Sometimes ago I ordered this ballmill from Pyrocreations: It has an internal barrell diameter of 103mm and a capacity of 0.8l. The working voltage is 120V, but since I live in Italy, I was forced to buy a transformer 120 -> 220V The first issue of this very cheap ballmill was the rotation: only 45 RPM!
