Best Quality Excellent Mechanical Performance Mining High Chrome Grinding Steel Ball
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.
Our grinding steel balls have many excellent properties, such as high hardness, light specific gravity, high toughness, less broken, great shock-absorbing, high performance of anti-fatigue and the strong ability of shocking hardened layer.
