Industrial grinders, of the sort used to produce espresso pods or supermarket packs of preground coffee, are more or less exclusively roller mills. The most sophisticated of these grinders can grind coffee without significantly heating the grounds, and in the process produce very narrow particle size distributions with minimal fines. This makes roller mills ideal for grinding coffee, except ...

Jet mills (also called air jet mills) have a special feature: they do not need mechanical grinding tools. Instead, the particles are crushed and ground in a gas stream by repeatedly colliding with each other there. Jet mills are an excellent choice in industry when ultrafine grinding is required. They are suitable for dry and very hard ...

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.
