How To Calibrate A Woven-Wire Sieve

Woven-wire sieves with inconsistent aperture sizes can make your dry sieve testing results inaccurate, which can affect your product's quality. Yet most users of woven-wire sieves do not check the aperture sizes of new sieves before using them and don't have objective criteria for determining when the sieves are no longer accurate and should be discarded. This article presents some methods for calibrating woven-wire sieves and monitoring their performance during use. Sections discuss the microscopic examination method and a new method for calibrating a woven-wire sieve.
