Grinding Media Specifications:

Kemcore grinding media are manufactured to exact specifications at two grinding media production facilities in Jinan, China. The balls are manufactured from high carbon low alloy steel bars and then forged into balls. The steel forged balls are produced visa air hammer, roll forging for larger diameter SAG balls and rotary rolling for mining grade grinding media.


Optimum wear and impact resistance are the main considerations in controlling the chemistry and microstructure during the production process. Our steel forged grinding balls in the diameter range of 1"-3.5" are primarily used in ballmill and re-grinding applications.


Quality Standards

Products manufactured in China. Certified under ISO 9001 Quality Standard and ISO 14001 Environmental Standard.


Our forged balls come with the following guarantees:

 Breakage guarantee:


  1. Up to 1% - no replacement
  2. 2-4 %-replacement of broken balls of the diameter concerned
  3. Over 5 %replacement of the complete mill charge


Proven Wear rates of:

  1. Proven wear rates of 0.70 kg/t.
  2. Recorded relatively high average grind efficiency of 15.28 % for 106 μm and 18.45 % for 300 μm.
  3. Forged Steel balls tested: 50mm and 60 mm forged steel balls
