Quantifying particle attrition

2019-12-11 · Ball-mill testing. Ball-mill attrition testing, as shown in Figure 2, uses large, heavy balls (typically metal or stone) in a rotat-ing drum to impose stress on par-ticles per ASTM C110. 3. The rotating drum causes the balls to lift then fall back into the particle bed at the bottom of the drum. Drum-roller testing is similar to ball mill attri-
