Factors that cause steel balls for ball mills

      The ball mill equipment is a common crushing equipment in the minerals. Steel balls are the main grinding medium of ball mills. During the long -term abrasive, steel balls will inevitably produce corrosion wear. 讲 Mine machinery explains the process of corrosion and wear of the ball mill steel and the phenomenon of steel ball micro -dynamic wear and preventive measures. I hope it will be helpful to users.

      When the material acts in the ball mill steel balls in the activity or corrosive grinding, the corrosion and mechanical wear will also cause the loss of the ball mill accessories and have the role of mutual promotion. The ball abrasive steel ball loss generated under this condition is often called corrosion wear. The corrosion products produced after the material or electrochemical reaction occurred after the steel ball friction surface of the material and the ball mill, generally the combination of the surface of the mother's body is weak. When the surface of the ball mill steel ball interacts with the material, the corrosion product is easily worn away, and the new exposure shows a new exposure. The metal surface provides conditions for further corrosion. In this way, corrosion -wear -corrosion alternately will cause metal loss higher than dry grinding.

During the wet operation of the ball grinding machine, the wear of the ball mill steel and the ball mill lining plate, the wear of the sand pump and the impurities pump impeller and the shell, the wear of the engine cylinder set is corrosion and wear.

     The mechanism of corrosion wear is more complicated. Due to the diversity of environmental media, mechanical wear and corrosion wear alternation, there are many factors involved. At present, it is difficult to propose a mechanism that can summarize all aspects. Know. Now it is understood that the three main factors that produce corrosion and wear of the ball mill steel are: the nature, environment, and temperature of the ball mill steel ball.

     Detailed understanding of the internal and external factors that cause corrosion and wear of the ball mill steel ball. In the application, the appropriate environmental temperature selection according to the material conditions and the nature of the ball mill steel ball can reduce the corrosion and wear of the steel ball and the ball.
