Chat Online### Top 5 product-specific milling technologies used in

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.
