Key Specifications:
– Diameter: 60mm
– Hardness: HRC 60-65 (Rockwell Hardness Scale)
– Material: Typically high-chromium cast iron or forged steel (depends on application)
– Application: Used in mining, cement plants, and ore processing for grinding raw materials or minerals.
Performance Features:
1. High Wear Resistance: HRC 60-65 ensures long service life under abrasive conditions.
2. Impact Toughness: Balances hardness with resistance to cracking during collisions.
3. Corrosion Resistance: Suitable for wet grinding environments if made with high-chromium content (e.g., Cr 10-30%).
Common Standards:
– High-Chrome Balls: ASTM A532, DIN 1695, GB/T 17445.
– Forged Ste.jpg)
Balls: Usually meet industry-specific hardness and impact standards.
Applications:
– Mining (gold, copper, iron ore)
– Cement production
– Power plants (coal pulverization)
Selection Tips:
– For high-impact conditions (e.g., SAG mills), ensure the balls have adequate toughness alongside hardness.
– Verify chemical composition (e.g., Cr, C content) for corrosion resistance in slurry environments.
