Corrosion Properties of Cast Iron Ball Materials in Wet
Microstructure of steel or cast iron balls may also influence the formation of oxide films. The corrosion reactions involve oxidation of iron at the abraded areas and reduction of oxygen at the unabraded areas. Another type of corrosive wear occurs during wet grinding, which involves galvanic interaction between the electroactive minerals and

What Is a Ball Mill?
Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps
