Ball Mills - Mineral Processing & Metallurgy
The center of the grate discharge end of this mill is open to permit adding of balls or for adding water to the mill through the discharge end. Instead of being constructed of bars cast into a frame, Grates are cast entire and have cored holes which widen toward the outside of the mill similar to the taper in grizzly bars.
Homeopathic Medicine - Methods of Preparation by Michael Quinn
For those materials which are insoluble in water or alcohol we need to triturate, or grind, these materials for many hours according to the directions of Hahnemann and the HPUS. Traditionally this was done manually by grinding the material in a mortar and pestle. We do this work with a mechanical device called a ball mill.

When the ingredients have been thoroughly mixed, and / or reduced in size, the resulting composition then has the capability of being used for propellant, without a cooking step.
Ball Milling - an overview | ScienceDirect Topics
Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
