Grinding Mills an overview ScienceDirect Topics
A jet mill grinds materials 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
