In the production process, the vibrating feeder will also have some common failures, which affect the normal feeding operation, thereby affecting the production operation of the entire production line. Let's take a look at several common faults and solutions of the vibrating feeder: 1. No vibration or intermittent operation after the ...

In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm. Therefore, in high-throughput and complex environments, the problem exists that harmful feeding materials such as iron and gangue are not easily detected, and thus fault …
