ABSTRACT:
A novel comminution apparatus and method for comminuting a granular feed into a product having a predetermined particle size. The comminution apparatus includes a high-speed cutter member operating inside a screen enclosure having adjustable openings in the screen enclosure. A lever arm is used to adjust the relative openings between an inner screen and an outer screen of the screen enclosure with the size of the openings in the screen enclosure predetermining the particle size range passing therethrough. Rotation of the cutter member creates an air flow outwardly through the screen enclosure while an air recycle system directs the airflow across the outlet to a feed hopper to carry the particulate feed into contact with the cutter assembly.
