Description
Technical Field
[0001] This utility model relates to a vibrating screen feeder for transporting bulk materials in steel plants, and belongs to the technical field of vibrating feeder equipment. Background Technology
[0002] Vibrating feeders are commonly used feeding equipment in steel plants, mostly installed at the outlet of silos. Their main function is to uniformly transport materials from the silo to other transport equipment at a certain speed. Generally, steel plants add a vibrating screen during the transport of bulk materials to remove excessively small powdery materials. However, many steel plants face limitations due to area planning and site constraints, making it impossible to add a vibrating screen before the vibrating feeder. This results in the inability to remove excessively small powdery materials from the bulk materials, which are then fed out along with the normal lumpy materials, reducing the feeding quality of the vibrating feeder and affecting the normal operation of subsequent processes. Therefore, it is essential to add a screening function to the vibrating feeder to remove excessively small powdery materials from the bulk materials. Utility Model Content
