	7.3 T/m³	64	7-10 J/cm²	B+A+Carbide	≤Φ100	≥18000
					>Φ100	≥15000
Characteristics:	High hardness, good wear-resistance, light in weight, energy saving, neat appearance, external hard inside tough, not broken.

Material and physical properties for the grinding balls

1) Material:

The grinding ball is prepared by nodular irons containing alloying elements such as nickel, molybdenum, chromium, copper and so on.

2) Physical properties:

The grinding balls show higher hardness (surface hardness of HRC60. After using, the surface hardness of the balls is about HRC64.) and good impact toughness of 7~10 J/cm2.
