ecomax 1


Name: Ecomax®

Ecomax® balls are low chrome balls submitted to different heat treatment (quenching, tempering, pearlitisation) to obtain the right structure. They are available in both forged, rolled or cast form.

  • Ecomax Cast®: cast balls
  • Ecomax forged®: forged balls


  • Mining
  • Coal grinding
  • Other wet applications

Equipment: Ball mills

Tech Specs:

  • Diameters: 26 > 150 mm (1” to 6”)
  • Surface hardness: 55 – 65 Rc
  • Volumetric hardness: 54 – 65 Rc
  • Cr nominal %: 0,15 – 1,1
  • Delivered in drums, big bags or in bulk

Key Benefits:

  • Cost effectiveness.
  • Low initial investment.
  • Low cost value.
  • Lower chromium content when chromium content in the final product is a concern.
  • Important: note that a Low Cr cast ball is as resistant as a forged ball.
    The right alloy for the right application to obtain optimum grinding efficiency and pulp chemistry at the lowest possible cost.
