Dynamic design theory and application of large vibrating screen

 — Dynamic optimal design of vibrating screen The initial force mainly distributes on the side plate and cross beams when the vibrating screen works. Then it makes a rigid motion and elastic deformation which generates a greater dynamic stress on the side plate and leads to fatigue crack of the side plate [11] . Adding stiffeners to base structure ...

What Is A Vibrating Screen?

 — The purpose of the vibrating screen is that particles are introduced to the gaps in the screens repeatedly. The frequency of the screen must be high enough so that it prevents the particles from blocking the apertures and the maximum height of the particle trajectory should occur when the screen surface is at its lowest point. Based on the ...
