The original ball load in the mill was 6614 lb. (3000 kg.) and the load at the end of the 694 hr. was 6338 lb. ( kg.). During this time, 590 lb. ( kg.) of balls less than 3 in. ( mm.) in diameter were discarded from the mill. The screen analysis of the ball charge at the end of the operation is shown in Table 20.

The new ball loads showed about the same superiority in the plain cylindrical mill as in the other mills. Thus far the evidence of the efficacy of a rationed load in plant operation may be questioned because, as is shown by tables 30 and 31, the coarse sizes were not reduced as much as with the Davis load.
