Acceleration of particle breakage rates in wet batch ball milling
Conclusions. Laboratory batch ball milling of 20×30 mesh quartz feed in water for a slurry concentration range of 20% to 56% solid by volume exhibited an acceleration of specific breakage rate of this size as fines accumulated in the mill. A quantitative measure of this acceleration effect was expressed in terms of the acceleration factor ( κ ...
