The effect of using concave surfaces as grinding

2000-1-1  Grinding efficiency is expected to increase with the increasing available surface area of the grinding medium. A grinding ball with concavity has a smaller volume than a sphere of the same radius. Therefore, the convex-concave ball has a smaller mass with the same surface area, providing a larger specific surface area and a greater charge density.
