Speed Stroke of a Linear Motion Vibrating Screen

May 31, 2013  I'm currently working on a vibrating screen design and could do with a little bit of help with specifying the appropriate speed slope. The application is screening trash (sticks, roots etc) from an iron sand slurry down to a size of 5mm. The screen bed is about 4.8m x 2.1m with a downward slope of 5degrees. We will be using linear motion exciters.
