WEBThe authors concluded that ball mills with a diameter of less than 600 mm do not have impact effects because all the wear occurring will be abrasive in nature. Thus, it is yet to be determined whether the impact levels in industrial mills that cannot cause macroscale fractures in white cast irons do or do not promote microfracture wear mechanisms.
