    Oct 16, 2015  Empirical formulas for estimating screen capacities in sizes below 0.25 mm (fine screening) are increasingly unreliable with diminishing particle size. Most of the formulas are approximations derived from a combination of test data, field experience, plain guesswork, and an assumption that the variables are logarithmic functions.
