Design Of Critical Speed For Crusher

A method of operating a rotorequipped breakercrusher for coal and other material in which the drum is rotated 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.
