Universal Mills efficiently enable one-pass grinding ... Replacing combustible gases and air in a process machine, with an inert gas such as nitrogen, CO2". Most common application is to remove air, which contains 21% oxygen and therefore makes air a good fuel to burn after ignition. No air helps ensure no flame or explosion.

Jet Mills. A jet mill, or fluid energy mill, grinds material by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size, while continue milling particles above that size, resulting in a narrow size distribution of the resulting product.
