Even milling it in an inert atmosphere would work fine (and N2 might not be 'inert' enough). I wasn't milling, only 'tumbling' it to mix it with a dilutent. It caught fire (exploded is the wrong word), and expelled all the contents into the air, where they all caught fire, causing that large fire plume.
