This tight control of the particle size is achieved by the fully adjustable rotor speed, airflow rate, feed rate, and classifier speed ...
Typically, the mill throughput will increase between 6 and 9%, if you have a variable speed mill. Liners are often designed with this in mind. The trend in mill liner shapes has changed from olden days when the liner/lifter pitch set = 2 x mill diameter in (ft.). Today, the liner pitch set should be half that ancient value or less.
