size distributions in AG/SAG mills. The existing models and understanding of grate discharge and classification are known to be flawed and have been identified as one of the key limitations in AG/SAG modelling. The aim of this thesis is to improve on the current understanding of discharge in the SAG/AG model.Mill (grinding) Wikipedia. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the The largest SAG mill is 42' (12.8m) in diameter,

down menu. The mill diameter input relates to the inside-shell dimension. The model actually requires the inside liner diameter and hence the liner thickness must also be input. The required length to be input depends on whether the mill is an overflow or a grate discharge machine. In all cases AG and SAG millsGearless mill drive (GMD) technology has further expanded the use of large SAG milling allowing Outotec to produce the world's largest SAG mill of 42' in diameter drawing power at 28 MW.
