Screening

The secondary spring suspension (standard on all Mesabi Screens) “floats” the entire working screen on a set of dual springs at each corner of the frame. The heavy bottom spring carries the weight of the screen and the downward thrust, while the smaller top spring absorbs the upward thrust for a smooth vibrating action.

Selection of Coil Spring for Vibratory Screen

Aug 11, 2012· The spring alone has a natural freq of around 52Hz. For the spring-mass system I used the formula for natural frequency of 3.13*[(K/W)^.5] where K is the spring-rate and W is the system weight. So Fn = 3.13*(195/(2265/8)^.5 = 2.59Hz for a natural frequency of the system.
