A Ball-on-Block Impact-Spalling Wear Test and Results

As new mills were made in larger diame- ters and rods and balls were made larger, impact forces become more severe on mill liner materials. In addition to break- age, the alloyed white irons have a pro- pensity to spall when subjected to re- peated impacts. One spall may represent a

Ball Mills - an overview | ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
