How ball mills work. A ball mill grinds material by rotating a cylinder filled with media (typically metallic or ceramic balls) mixed with a continuous flow of feed and recycled material. At slower rotational speeds, the grinding media creates a cascade motion where the media is mainly rolling and shear forces for grinding are generated.
Selecting the right ball mill media is essential for optimizing the grinding process and achieving high-quality black powder. Several factors should be considered …
