Grinding Media Hot-rolled Steel Ball

4. Permanent in shape: our balls wont be out of circularity from start until finish.

Detailed properties are as follows:
1. High whole hardness: the surface hardness could be HRC 60-65, the average volumetric hardness could be HRC 60-63, and the hardness gradient is uniform.
2. High notched bar impact strength: it is more than 17J/cm2
3. Low breakage rate: Properties for peel &breakage resistant are more than 10 times than traditional steel ball. There is almost no breakage when ball impact more than 200,000 times. Actual breakage rate is less than 1%.

Our company is specialized in manufacturing hot rolled grinding balls according to Forged (Rolled) Steel Balls Ferrous Metallurgy Industry Standard (YBT 096-2005). 12 different sizes of balls with diameters ranging from 20mm to 100mm are available.
The product has following advantages: wear-resistant, permanent in shape, cracking-proof, which can be widely used in large scale mine, power plant, cement plant and the other industry. Our customers both at home and abroad appreciate our balls.
The major advantage of precision ball rolling, compared with traditional forging methods, is the uninterrupted grain flow. Grinding balls and cycled are rolled from selected carbon and alloy steels produced to precise specification. A special feature of the manufacturing process is the advanced quench facility, giving uniform surface hardness and controlled cross-sectional hardness essential for very even wear.
