Ball mills are used to produce calcium carbonate. The ball mill is a type of grinder that uses balls to grind materials into very small pieces. The balls roll around inside the mill, which grinds the material into tiny pieces. This process helps to break down the material so that it can be used in other products. Calcium carbonate is a common ...
Biogenic calcium carbonate from waste mollusc shells can be amorphized in a species-specific mode by ball milling mechanochemistry.
