Best Quality Excellent Mechanical Performance Mining High Chrome
Grinding Steel Ball
Product Introduction
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.
