moreIndustrial Screening. Barry A. Wills, James A. Finch FRSC, FCIM, P.Eng., in Wills' Mineral Processing Technology (Eighth Edition), 2016. Industrial screening is extensively used for size separationsfrom 300 mm down to roughly 40 µm,although the efficiency decreases rapidly with fineness. Dry screening is generally limited to material above ca. 5 mm in size, while wet screening down to ca. 250 µm is common.
