The type of the ball mill used should be considered as an important factor. It is believed that roller ball milling leads to bring more contamination to the powders when compared with the roller rod mills. [8] This can be understood from the difference in the mechanisms between the two categories of mills, as previously discussed in Chapter 3.

Hammer Milling and Jet Milling Fundamentals | AIChE

A hammer mill is typically good for grinding softer materials with Mohs hardness 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.

Jet mill Wikipedia

Jet mill Wikipedia

A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. [1] Jet mills can be designed to output particles below a certain size while continuing to mill particles above that size, resulting in a narrow size distribution of the resulting product. [2]
