ABSTRACT:
A rotor-equipped breaker/crusher drum for coal and other material in which means are provided for rotating the drum at close to critical speed, and in which lifter shelves in the drum are adjusted for dropping material into the path of the rotor at a point where the rotor not only fragments the material, but also emphasizes the flinging of the material against the downwardly moving perforated wall of the drum. Apparatus of this character enable a relatively small breaker/crusher to effectively duplicate the performance of much larger existing units, while successfully controlling the production of fines.
