Factors That Affect the Grinding Effect of .

Overflow ball mills rotary speed influences the motion state of steel balls. Under the low-speed circumstance, steel balls drop after rising to a certain level, with grinding as main acting force supplemented by the impact. If increasing the speed, steel balls are thrown and fallen, with impact as main acting force supplemented by grinding.
