High Quality Wholesale and Custmoized Grinding Steel Balls for Mining
High Chrome Steel Grinding Media Balls is used in mining where they are used to extract precious metals in ore mineral processing. Since ore particles must go through the grinding process, steel grinding media are ideal for such a grinding process. Steel ball grinding media are made from alloys of iron and carbon. By increasing the carbon content to produce cast irons, both the hardness and wear resistance are improved significantly.
