Vibrating Screen Problems Solutions

Improve The Motion Mode Of Screen Deck

The motion mode of screen deck also has great influence on the screening efficiency of vibrating screen. The ideal motion mode of screen deck is:

The vertical vibration amplitude of the feeding side should bigger than the vertical vibration amplitude of the discharging side. This is because large vertical vibration amplitude of the feeding size can make the thick raw materials in the feeding size effectively layered. At the same time, because of the inclination angle of screen deck, the raw materials at the feeding side will spread to the middle of the screen deck, which greatly improve the actual usable area of screen deck. When the raw materials move to the discharging side, they already got layered, so we only need small vertical vibration amplitude to make them separated and through the mesh.

Along with the length of screen deck, from the feeding side, the movement speed of raw materials should decrease progressively. This can also increase the actual usable area of screen deck.

Adopt Non-Metallic Material To Make Screen Mesh

To improve the screening efficiency of vibrating screen, we can also adopt a kind of thin elastic screen mesh, which generally made of rubber or polyurethane material. This kind of screen mesh can effectively reduce the adhesion force between screen deck and raw materials, avoiding the block of screen mesh.

Adopt Multiple Feeding

Generally, we adopt only one feed opening, when the raw materials are sent to the screen deck, particles below partition size will through the screen mesh quickly. The utilization rate of screen deck is low. But if we adopt multiple feeding, it is like we increase the width of screen deck and reduce the thickness of raw materials on the screen deck. In this case, the fine particles will quickly through the screen mesh and the transportation distance also reduced.

Strengthen The Operation Management

The operation and maintenance of vibrating screen also affect the screening efficiency to some degree. In order to ensure the high screening efficiency of vibrating screen, operators should strictly follow the operating rules. Besides, the raw materials should be fed evenly and continuously. In addition, operators should strengthen the maintenance and repair of vibrating screen, such as clean the screen deck timely, repair or change the brock screen deck etc.
