A CRITICAL REVIEW OF GRINDING DESIGN …
• Transfer size (T80) is the term used to describe the SAG mill product that is sent to the ball mill. For peak performance and balancing the power available in the SAG mill and ball mill, the transfer size must be measured and controlled. • The transfer size will be 500 microns using a 12mm opening trommel. This can be true under special
