• 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

Ball-Mills Versus End-Mills for Curved Surface Machining
The use of end-mills for machining low curvature surfaces is examined in relation to the more popular ball-mills. End-mills are shown to give a better match to the required surface geometry and hence reduce the number of surface passes required. They also have a much better efficiency of material removal and longer tool life. It is shown that the use of end …
