Ball Mill (Ball Mills Explained)
Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit).
What is a Semi-Autogenous Mill?
A semi-autogenous 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. Semi-autogenous mills use a minimal ball charge of 6 to 15%.
