Design and Performance Assessment of a Double-Screen …
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%.
