Abstract: With the high G value of vibration, outstanding sieving behaviors of a flip-flow screen are more likely to appear, but structural damages are aggravated under the high amplitude vibration. Considering rubber springs role on the vibration energy dissipation, viscoelasticity of rubber springs (i.e., shear springs and vibration isolation springs), is …

This means that the benefits of both vibration types are combined in a horizontal screen. Horizontal screens have a stroke range of 14–20 mm and typically run at a stroke of 16–18 mm and a spinning speed of 750 rpm. Between 0.2 and 0.25 meters per second, materials move through the screening medium.

Suspension is either by means of steel coil springs or moulded rubber buffers. Buffers have higher dynamic loads but are more suited to wet applications. The number and types of buffers or springs is determined by the mass of the screen. 2. Vibrating mechanism Screens are vibrated in linear motion using geared

The dynamic response of the vibrating screen has a great impact on the screening efficiency and fatigue life of the structures. For the conventional dynamic design, the consideration of the influence of load weight on dynamic response is lacking. So, in this paper, taking a very common vibrating screen used in tunnel construction as an …

Springs of vibrating screens are prone to fatigue induced failure because they operate in a heavy duty environment, with abrasive dust and under heavy cyclic loads. If a spring breaks, the stiffness at supporting positions changes, and therefore the amplitude of motion and the static and dynamic angular inclination of deck motion also change. This change in the …
