Screening: In its simplest configuration, a screen is a hard perforated surface with a matrix of fixed dimension apertures. The material is presented to the screen surface so that material finer than the apertures falls through the screen and the oversize is conveyed to the discharge end of the screen. Screening is generally difficult below 0.5 mm.
