An iron ore mill relies on the grinding and impact of grinding balls to complete iron ore crushing the operating process of an iron ore mill is as follows first the ores are poured into the mill and both the ores and the grinding balls are lifted by the lifting bar arranged on the wall of the cylinder body to a certain height after which they fall onto the bottom of the mill to complete.
