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

Vibrating screens are often used in the mining industry to separate mineral particles by size. In many designs, spring arrays are used to provide the system with the necessary stiffness for screens to vibrate in a controlled manner. Naturally, these springs are subjected to varying loading cycles, which can cause their premature fatigue failure. This behavior has been studied by means of finite element analysis

Vibratory Screens. Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification
