But remember it all depends on your mill feed size after pregrinding This is the raw mill not the finish mill So Wi should be 11 and density of as normal kiln feed I used d80 of 3500 micron to be on safe side and got max ball dia of 41 mm use 50 mm steel balls

Casting defects will lead to premature failure of the grinding media during mill operation as shown in Figure 2 Figure 2 Photograph of OTHERS casting balls showing Fracture in the mill The casting defects will also have detrimental effects on both impact and abrasion resistance of the grinding ball The impact fatigue resistance is very important and needs to be controlled by a proper heat
