Product Description

1.Forged Steel Ball Features and Advantages:
Concentrating on wear-resistant grinding material for 30 years, Huamin Brand steel grinding ball is excellent in surface quality, hardness, and resistant to impact and abrasion. It won't crack and lose circularity easily.
1) High Hardness: Huamin forged grinding steel ball has high hardness: surface hardness can reach to 55-67 HRC, volume hardness 56-64 HRC
2) High Impact Toughness: impact toughness is more than 12 J / cm2.
3) Low Broken Rate:  peel fragmentation resistance property of over 20000 times. The actual breakage rate is less than 1% and close to 0.

2.Grinding ball for initial assembly SAG mill refers to the grinding balls charged in the mill before the SAG mill reaches the design capacity(or normal production). Due to the instability of operating parameters,worker's proficiency,feeding mineral and frequent impact between balls and liners,these circumstance maybe induce breakage of grinding balls or liners to reduce their service life,which affect trial production and increase additional charges.

After many investigations and tests, based on mine condition, we has developed the grinding balls for initial assembly SAG mill. The performance of the grinding ball is adjusted through the improvement of the material and the matching heat treatment process.These grinding balls with high toughness and suitable wear resistance could ensure design capacity though adapting to such extremely harsh working conditions and reducing impact on the liners. Through the practice in mines shows, it has greatly promoted production designed and reduced costs.
