Based on the experimental analysis, an empirical model to predict the depth of cut was proposed.
Jet milling as well as its feed rate were of great importance. • Particle size affected the composition and mechanical properties of flours. • The solvent retention capacity profile was also affected by particle size. • The effect of particle size depended on the botanical origin of the flour.

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.
