Definition of wet-and-dry screening Mindat

Definition of wet-and-dry screening. In sizing analysis of fine material, preliminary screening by washing a weighed sample on a 200-mesh screen, perhaps with use of a dispersing agent, such as sodium silicate. Removal of the minus fraction (which is settled and later brought into account) is followed by drying of the on-size and by standard sizing

Vibratory Screens McLanahan

Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification. Material must go through or over a specified size to end up in the
