When depth of cut is less than the radius of a ballnose, a little thought and perhaps a visual shows that the full diameter is not engaged, but just the diameter out near the end of the ball. Yet, he had a situation where the ball was down in a slot, and this is what was worrying. He sent this diagram to illustrate:
The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Length-to-diameter= 1.4 to 2.3. Mill length = 7 meters. Rod Mill-Ball Mill Circuits Diagrams of mill circuits [image: (135-8-2)]
Calculate Top Ball Size of Grinding Media -FRED C. BOND Equation & Method Previous Next Although it was developed nearly 50 years ago, Bond 's method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills.

Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40 K√F

the final product size. The prediction of the SAG mill transfer size used in the formula is made by comparison with pilotplant data and operating plant data for similar ore types (Barratt, 1989). The approach acknowledges grinding efficiency as the ratio of operating work index to that for a single-stage ball mill.
mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.
The SAG mill product is then crushed to passing 3.35 mm and is subjected to the Bond ball mill work index (S d-BWI) grindability test to provide the total pinion energy at the specified grind size for mill design purposes, herein reffered to as micro ore hardness. The full SAGDesign test produces the SAG grindability (W SDT) and the Ball Mill
