Although hammermill capacity will vary with the type of machine and operational parameters, air assisted grinding systems will out produce non-assisted systems by 15-40% (Figure 11). A good rule of thumb for the amount of air required to assist product and control dusting is 1.25- 1.50 CFM/In2 of screen area.
