A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.

Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...

A smaller ball interpolated exposes more of the surface to a faster moving cutter, leading to a better finish. But, the smaller cutter can flex more. Hence the need to balance these two factors. If you have a 4th axis or 5axis mill, you can try "Sturz" milling to combat the slow moving tip. See below for details.
