It's all about the fan. Air swept mills are used primarily when grinding light, relatively nonabrasive materials to a mid range to fine particle size because lighter particles require suction to overcome the rotor airflow. The fan pulls the material from the mill infeed through the grinding chamber. In

The conventional model for grinding in tumbling ball mills was modified to allow for airsweeping, for the case where all the material is carried out of the mill in the air stream. It was shown that this type of mill can be treated as a single fully mixed reactor. The values of the internal classification numbers given by the airsweeping were ...
