Anyone wondering how Bond ball mill work index compares versus SPI or JK A*b? Well, M. Doll says, several comparisons have been published, such as at CMP 2011 and Procemin 2009 and in general, the Wi_BM is not compatible with the other two because they measure different size classes. The Bond ball mill work index measures …

A ball mill consists of a hollow cylindrical chamber (Fig. 11.2) which rotates about a horizontal axis, and the chamber is partially filled with small balls made of steel, tungsten carbide, zirconia, agate, alumina, or silicon nitride having diameter generally 10 mm.The inner surface area of the chamber is lined with an abrasion-resistant material like …

Although the true wear test of a grinding ball is its life in a real ball mill, the laboratory tests of impact and abrasion may serve as a guide to expected ball life. The two most significant differences found among the commercial balls were the number of impacts to breakage and the impact-spalling rate.

The impact–abrasion–corrosion behavior of three typical wear-resistant steels including low-alloy wear-resistant steel, martensitic stainless steel and Hadfield steel for ball mill liner in simulated acid slurry was studied by impact–abrasion–corrosion test under high impact energy. The structure, mechanical properties and corrosion …
