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. •
of 154.2 ton/h. The trommel efficiency was also estimated, considering that the MSW has an average particle diameter of 152 mm and that each particle impacts, at least, 20 times with the trommel surface before passing through the mesh open area. Thus, for a mesh with an open area fraction of 0.51, the trommel efficiency reaches the value of 82%.
