Traditional designs of vibrating screens have a uniform field of amplitude over the entire surface of the sorting surface generally. Thus, the oscillation amplitude has the same value over the entire sieving surface, or a constant value in each point of the sieving surface. This phenomenon poses a number of problems of sorting of bulk materials, which, ultimately, do not allow to obtain ...
Classifiion Based on Sieving Vibrating screens The basic method of operation of a screen is very simple. The screen presents a barrier to the passage of oversize material while it readily passes undersize material. It is only necessary to ensure that each particle has an opportunity to reach the screen. In practice each particle is given several opportunities to pass through the ...

What I mean is : A vibrating screen ( 2 bearing design) has an eccentric shaft and 2 counter weights at the shaft ends. I would like to know what should be the amount of eccentricity on the shaft and how much should be the weights at the end...
appliions like vibrating screen separator, vibrating feeder and vibrating table. Certain machines and structures that develop excessive vibrations during their life and it may be required to make a diagnostic vibration analysis to prevent an impending failure of some of components. Such components can be tested using vibration exciters. Different types of vibration exciters are used for ...

Synchronous vibrating screens have been widely used in mining, metallurgy, petroleum and other industries, due to their simple structure and high efficiency [1, 2]. Blekhman [3] first proposed the synchronization theory of mechanical exciters in the 1950s. Since then, self synchronization theory has been introduced into many vibrating machines excited by two eccentric rotors. Zhao [4 ...
