Transfer Size, T80: Is the 80% passing size of ore as it passes from the SAG mill to the ball mill. It is typically about 1/3 the size of the screen opening but can be coarser than 1/3, especially when a pebble crusher is used. Screening at 5 mm ensures that the T80 will be about 10 mesh (1.7 mm) ensuring that the ball mill will work efficiently.
