Safety about ball milling aluminum powder

The right thing to be said upstairs must have gas protection

As long as there is gas protection, there is nothing.Even high energy, it's okay.But if there is no gas protection, there is a certain danger.
The ball mill is most afraid of magnesium powder, even if there is gas protection, it is easy to explode.I have heard of Tsinghua have an explosion, and I have exploded once. Fortunately, no one was there.So as long as there is no magnesium in your ingredients, there is generally nothing.But must have gas protection.

The ball grinding jar is generally equipped with AR protection, otherwise it will explode, combustion, etc.; After the ball is grinded, it needs to be cooled and opened in the glove box (AR atmosphere), which is safer!In addition, if it is a high -energy ball mill, be careful!
