2023年2月23日 The semi-autogenous mill is a new type of grinding equipment with both crushing and grinding functions. It has the advantages of simple process flow, small investment, short construction cycle, and easy operation. It can directly grind raw materials or coarsely crushed materials to 0.074mm. The grinding ratio can reach 4000-5000,
What is a Semi-Autogenous Mill? Ballmillssupplier
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%.
