High Chrome Casting Alloy Iron Balls Steel Grinding Media Balls For Power Station

 

 

1. Hardness: 60-65HRC

2. Size: 20mm-180mm/ 0.75''-6''

 

Used Mine, Cement Plant, Power Station, Chemical Industry, Ball Mill, Sag Mill

 

Casting Grinding balls are widely used in cement, mining and chemical industry etc..

 

The hardness reaches up to 64HRC(the surface and inner hardness tolerance with in 2HRC),

 

which makes the high wear-resisting property.

 

In addition, the distribution of the hardness gradient is average.

 

The property- low wear rate, good toughness, prolongs its life, improves the productivity of the ball mill,

 

and lowers user’s cost.
