air requirements for grinding mill

The Jet Pulverizer Company - Custom Processing & Jet Mills

In a jet mill, the temperature of the air leaving the jets is cooled to about -200 degs F due to the Joules Thompson effect and the product leaves no warmer than the air used for the grinding. (Friction from collisions and contact with the grinding chamber is offset by the cooling effect of the expanding air).Oxidizers and highly explosive ...
