High Energy Ball Milling In discussions on high energy ball milling, the more generic term "ball mills" is often used in place of the terms "stirred ball mills" or "Attritors," but the differences between the types of mills are quite distinct. And, depending on your application, you may find that one type of high energy
The test using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to P80 less than 100 mm.
The work using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to P 80 less than 100 μm.
Varied types/geometries of stirred mills have been produced by different manufacturers, and the comparison task has been accomplished for some of the technologies, i.e., Tower mill vs IsaMill. However, the main drawbacks of these comparisons were the uncommon characteristics of the milling environment, such as …
The present literature review explores the energy-efficient ultrafine grinding of particles using stirred mills.
