What does Ball Mill Do?

Wet ball milling is similar to dry ball milling, except that a certain proportion of water or absolute ethanol should be added according to different materials in the grinding process. It is mainly used for materials that will not affect the quality in the presence of water, such as non-ferrous metal ores such as gold, copper and copper.

Contamination in wet-ball milling

ABSTRACT. The top–down approach of mechanical ball milling/alloying is the most commonly adopted route towards materials development. It is however surprising that despite the large impact that it has, process induced contamination (particularly from process control agents (PCAs)), remains less studied and often ignored.
