WhatsApp: +86 18838072829A semiautogenous mill is a type of grinding mill that uses grinding balls and ore or rock fragments as grinding media. The grinding is done by the impact of the rocks or ore particles on themselves or on the grinding media, thus breaking the ore into smaller particles. Semiautogenous mills use a minimal ball charge of 6 to 15%.
