Particle Size Reduction and Enlargement - ScienceDirect

1/1/2019· The mill has an advantage over the compound ball mill in that the large balls are raised to the greatest height and, therefore, are able to exert the maximum force on the feed. As the size of the material is reduced, smaller forces are needed to cause fracture, and it is, therefore, unnecessary to raise the smaller balls as high.
