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. (2874.8 kg.). During this time, 590 lb. (267.6 kg.) of balls less than 3 in. (76.2 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 hardness of the liner and the grinding ball should be above HRC50. This is mainly because the hardness of the hard phase in the abrasive is 6 ~ 7 on the Mohs scale. It is estimated to be close to HRC60. In theory, the hardness of the grinding medium is greater than or equal to eight percent of the hardness of the abrasive.
