Efficient operation Thanks to the high material velocity, blinding is significantly reduced, and efficiency is increased allowing for a low total cost of operation Versatile applications MF Series™ banana screens configurable for varied slope degrees to fit any application and help you get the most of your operations Optimal uptime

" Efficiency" of Vibrating Screen is the ratio of the amount of undersize obtained to the amount of undersize in the feed Where 'E' is the efficiency, 'e' is percentage of undersize in feed and 'v' percentage of undersize in the Screen over size

Industrial Screens A 20° inclined screen is typically used for pre­ screening and sizing applications Decreasing the inclination slows the movement across the table thereby decreasing capacity but improving efficiency Above 12 mm, dry screening is preferred

Limitations of the high frequency vibrating screen are that the fine screens are very fragile and are susceptible to becoming blocked very easily Over time the separation efficiency will drop and the screen will need to be replaced An alternative to the high frequency vibrating screens is ,

Screen Stroke The shape and amplitude of the motion of a screen Usually screen strokes are circular, oval or straight line strok • Open Area The area available on a screen for a aggregate particle to fall through a hole in a screen Usually expressed as a percentage • Screen Efficiency
