High Chrome cast grinding media

Our chrome casted grinding balls vary in sizes from 40mm- 110mm with Chrome (Cr) contents of up to 28%. The choice of grinding media depends on a number of factors namely:

  1. The type of product being ground- Its relative work index, granulometry, density etc.
  2. Milling process- wet or dry application, closed system vs. open system
  3. Predominant type of wear within the mill- abrasion, high impact or corrosion.


We provide custom fit solutions for the various industries utilising grinding media depending on the above criteria. We pride ourselves in working together with our clients to ascertain the best suitable grinding media for them in the Mining, Cement and Power Generation Industries.

Each order produced is in accordance to customer specifications with regards to the following criteria:

  • Ball size
  • Cr content
  • Hardness (HRC)
  • Chemical composition
  • Packaging requirements

Each order is sent out with material data sheets specifying the chemical content and metallurgical properties of the product.
