Media sizing Ball mill media optimization through functional performance modelingBall bonding is the process in which pads are connected onto a die and leadframe (or substrate) using very fine diameter wire. The basic steps of ball bonding include the formation of: the first bond (normally on the chip),

000 µm. Note that—in order for no correction factor for ball mill product fineness to apply—the ball mill circuit P80 should be no less than approximately 70 µm (Bond repeat operation several times d 50 is the 50% passing size and the second bond (normally on the substrate). The wire-bonding cycle is shown in Figure 1.There is a mathematical solution to this problem – the Bond formula. It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure. The calculation formula is below: B – the …EF5BM=[ P80+10.3 1.145×P80] ( 3 ) The EF4 formula requires both the rod mill and ball mill work index (rod mill Wi is used to calculate the optimal feed size) and because this is a "single-stage ball mill" calculation,
