Jan 01, 2016 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 11 and 1.81 ...

Estimation of Specific Rate of Grinding to Optimize the

Ball mills are widely used and less carefully studied. It has been observed that in most cases these ball mills are operated inefficiently and much of the energy is lost. This results in longer than expected grinding times. The present study is taken to control the particle size distribution and reduce the specific energy consumption in an ...
