Calculate the number of turns of the spring based on the stiffness condition. Finally, the spring needs to be checked, and the initial tension, ultimate working stress, and ultimate working load of the spring are calculated respectively to verify whether it meets the requirements. In this way, the design of the vibrating screen spring is completed.

This screen is a double-deck linear motion vibrating screen with a size of 3.66 × 7.32 m and a 10.5 mm nominal stroke. The CAD model of this vibrating screen is shown in Figure 4(a), where the upper and lower screen decks, feed chute, and lateral and rear walls that serve as boundaries of the particles are detailed. The lateral wall on the ...
The main parameters of the vibrating screen are: elastic modulus E 2.068 = × 105 MPa, Poisson's ratio υ = 0 .3, density ρ = 7 .8 × 103 kg /m3, and axial stiffness of the spring 403 …
Spring failure is one of the critical causes of the structural damage and low screening efficiency of mining vibrating screens. Therefore, spring failure diagnosis is necessary to prompt maintenance for the safety and reliability of mining vibrating screens. In this paper, a spring failure diagnosis approach is developed. A finite element model of mining vibrating …
For efficient wet or dry screening—Hi-capacity, 2-bearing design. Flywheel weights counterbalance eccentric shaft giving a "true-circle" motion to screen. Spring suspensions carry the weight. Bearings support only weight of shaft. Screen is free to "float" and follow positive screening motion without power-consuming friction losses. Saves up to 50% HP …

Demand for large vibrating screen is huge in the mineral processing industry. As bending and random vibration are not considered in a traditional design method for beam structures of a large vibrating screen, fatigue damage occurs frequently to affect the screening performance. This work aims to conduct a systematic mechanics analysis of the beam …
Dry screening of viscous and fine-grained minerals is an urgent problem to be solved in processing coal ore, and iron or gold deposited rocks, etc [1], [2].However, conventional screening equipment (linear vibrating or circular vibrating screens) frequently encounter the problem of rapid blockage of the screen's apertures, which reduces screening efficiency [3], [4].
