TECHNICAL NOTES 4 VIBRATING SCREENS -

2009-7-30  The simple capacity model permits the calculation of the total screen area that is required for aspecific duty. The aspect ratio of the screen (length/width ratio) must be determined by consideringthe depth of the bed of particles on the screen. An approximate guide is the restriction of the beddepth at the discharge end to no more than 4 times the mesh size. The thickness of the bed isdetermined by the total flowrate over the screen surface, the width of the b,screen, and the velocityof travel of the material along the screen.
