    As like panning for gold, the fine particles tend to stay towards the center and the larger go to the outside. It allows for segregation and unloads the screen surface so that it can effectively do its job. With the addition of multiple decks and ball cleaning decks, even difficult products can be screened at high capacity to very fine.

  • Correlations for the grindability of the ball mill as a measure of its .

    The performance of a ball mill is measured with reference to the quantity of undersize or fines (amount of ground material passing through a 120 mesh screen) per revolution of the mill, collected for variation of each of the individual parameters. Finally, the calculated values of the fines in terms of the grindability of the mill.
