The Structure of Vibrating Screen ZS2560 is a linear vibrating screen widely used in coal separation. As shown in Figure 1, the ZS2560 linear vibrating screen is mainly composed of vibration exciters, screen box, and spring. The screen box is the main working part of the vibrating screen, and accordingly, it is vulnerable to the damage.

The main beam of the Vibrating Screen is the beam that supports the vibrator above the screen frame. Under normal circumstances, the vibrating screen of a box vibrator has a compacted main beam, and its working condition is critical to the life of the screen. However, the vibrating screen often comes off the main beam, which is not easy to repair after falling off, which seriously affects ...

A Theoretical Rigid Body Model of Vibrating Screen for ...

long-term alternating loads are likely to lead to spring failures, likely resulting in structural damages to the vibrating screen and resulting in a lower separation efficiency. Proper dynamic models provide a basis for spring failure diagnosis. In this paper, a six-degree-of-freedom theoretical rigid body model of a mining vibrating screen is proposed, and a dynamic equation is established ...

Structural Vibration and Ways to Avoid It Article

Once the facility is built, it is very expensive to modify the structural deck beams to fix a vibration problem. A better approach is to conduct a Structural Vibration Analysis of specific areas of the deck or platform. During the design phase it is easy to make minor changes to the beam orientation and design to avoid resonance. This dynamic analysis is coordinated with the vibration design ...

08.09.2015 · 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 structures and improve the design method.
