process. Screening As discussed above, most large facilities use mechanically cleaned screening systems to remove larger materials because they reduce labor costs and they improve flow conditions and screening capture. Typically, only older or smaller treatment facilities use a manually cleaned screen as the primary or only screening device

Figure is multiplied by the sq. footage of the screen deck. • Calculation gives the basic capacity of each deck and the total capacity of the vibrating screen. • The vibrating screen capacity is determined: • Using a standard sizing formula (9 variables). • Basic capacity of each deck opening. • Unique factors of that application. •

Screening Process: Grizzly, Trommel, Vibratory and Gyratory Screen Separator. The crushed particles are separated using a hard metallic screen with a perforated surface of fixed dimensions and uniform aperture. Crushed fragments of urban- mined material are dropped onto the screen surface

Screening and cleaning. The pulp is screened at high consistency using screen baskets with narrow slots. High pulp consistency minimizes white water usage and provides a low passing velocity through the slots, which optimizes screening efficiency. Shives and sand that do not pass the narrow slots, the rejects, are sent to the unrefined rejects
