A survey of 40 industrial mills in Australia found that the maximum ball mill diameter in use was 5.34 metres and length 8.84 metres . Autogenous mills range up to 12 metres in diameter. The length-to-diameter ratios indicated in Table 7.1 for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and 1.8:1 ...

at start-up: Monitor contact patterns, as the pattern could change under load-ing. Verify the gear set is lubricated properly. – As soon as the machine is run-ning, verify that adequate amounts of lubrication are conveyed and dispersed evenly and completely. A good suggestion is to run mill for eight hours under no load,
