Fine grinding size distribution analysis using the Swrebec function
Monosize quartz sand suspensions (53, 45 and 38μm) were prepared in water at 60% solids weight and were ground for a fixed period of 10min, in a lab ball mill (16Φ×18cm), with steel balls of 4, 3, and 2cm in diameter. Resulting size distributions were fitted to the Swrebec function. This function wa...

Summary: | Monosize quartz sand suspensions (53, 45 and 38μm) were prepared in water at 60% solids weight and were ground for a fixed period of 10min, in a lab ball mill (16Φ×18cm), with steel balls of 4, 3, and 2cm in diameter. Resulting size distributions were fitted to the Swrebec function. This function was initially proposed to fit coarse size distribution (as in the case of blasting and crushing processes), with an excellent correlation coefficient, showing that this function can be used with good results in fine grinding.
[Display omitted]
•The Swrebec model fits PSD not only in coarse size range.•The Swrebec model fits PSD also in fine grinding size range.•The fitting yielded high coefficient of correlation.•Further research is conducted to integrate the PSD model in breakage models. |
