Shape Retention

Hira 92% High Alumina Balls

Why is the spherical shape of grinding media so important?

  • Efficient rolling and cascading effect in the mills

  • Uniform Particle Distribution

  • Faster and Effective Grinding 

What are the benefits of longer shape retention?

  • Decreased Grinding Media Replacement Cost

  • Decreased Machine Downtime

  • Increased Mill Lining Life

  • Increased Fixed Costs and per unit cost of Output

  • Decreased Productivity
