Berry and Bruce (1966) invented an approximate procedure where the data of an unknown ore grindability are compared to reference ore of known grindability. This procedure can be carried out in any laboratory ball mill. Horst and Bassarear (1976) gave a similar procedure, but lasting a bit longer, where reference ore data and data of

The feed size of an ore to a 1.7 m × 1.7 m wet ball mill operating in closed circuit was 5000 μm. The work index of the ore was determined under dry open circuit conditions and found to be 13.5 kWh/t. The mill bed was filled to 30% of its volume with balls of density 7.9 t/m 3. A 20:1 reduction ratio of ore was desired.

The "pulverisette 4" vario-planetary mill is capable of emulating ball mills of conventional design, simulating the types of stress entailed and thus reproduc-ing or optimising grinding processes. Due to the high flexibility available for se-lecting the grinding parameters, it is possible to achieve results unattainable with any other ball mills.

Regular ball sorting is a must to maintain tube mill efficiencies and avoid losses of up to 10-20%. The quality of the sorting and its frequency are both critical. 1 st chamber: balls below a specific dimension have to be rejected to avoid overloading or even back spilling effects. Sorting to repeat every 1-2 years

parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change. • Population balance modelling was deemed unsuitable for this purpose.
