Improvement of grinding media has been a slow process. Grinding balls can be evaluated by the user by keeping records of ball consumption and ore tonnage. But this procedure requires long testing times of months or years (Norman, 1948; El-Koussy, et al., 1981; Moroz and Lorenzetti, 1981; Howat, 1983; Malghan, 1982).

Advantageously, the grinding aid composition minimizes the agglomeration of cement particles as well as their adherence to the surface of grinding media (e.g., steel balls used in a grinding mill) thereby improving the energy and comminution efficiency of the grinding process.
However, your choice of media composition should factor in the compatibility with the type of materials being ground as well as the ball mill lining to ensure the highest efficiency. Apart from composition, you should take some other properties of ceramic grinding media balls into account.

High Chrome Alloy Grinding Media Balls' Chemical composition As far as chemical composition, there are dozens of different materials from low chromium to high chromium.
Secondary Grinding – Ball Mills. In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [< 2½", (65 mm)] typically used in secondary milling environments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear.
Chrome Steel Grinding Media Balls Description. AISI Type 52100 Chrome Steel Grinding Media Balls are used in the dry grinding and milling applications where corrosion resistance is not required. When corrosion resistance is required, 304 or 316 stainless steel grinding media balls should be used.
SIZE: SAG milling grinding media are available in sizes from 4.0" to 6.5" or 105 mm to 160 mm. CHEMISTRY: The chemistry of the balls is controlled via a robust internal quality system with our bar suppliers to optimize physical properties.
