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 ...

The SD Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation, the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.
