The Flip Flop Screen is a special screening equipment designed specifically for handling fine, sticky, and wet materials that are difficult to screen, such as the medium and fine particle size classification of highly viscous raw coal and coke. The core principle lies in utilizing the tension and relaxation movements of the screen surface, ensuring that the screen holes are not clogged, and achieving efficient screening.
Flip Flop Screen Screen Mesh
The flip flop screen screen mesh is a key component of this device, and its material is polyurethane elastomer. This material exhibits excellent mechanical properties due to its unique structure.
- ► Firstly, the wear resistance of polyurethane is extremely high. Its Tabor wear value is much lower than that of natural rubber.
- ► Secondly, within a wide range of hardness, polyurethane shows high elasticity, with an elongation rate of up to 399% - 799%.
- ► Moreover, it also has strong load-bearing capacity and vibration-damping ability.
- ► What's more important is that polyurethane is resistant to oil and corrosion, making it widely used in various industries such as mining, oil fields, machinery, and textiles.
However, although polyurethane screen mesh has excellent performance, due to the back-and-forth or facing-and-facing movement of the crossbeams on both sides of the screen surface, the screen surface will exhibit periodic tension or relaxation. Under the action of alternating loads, the screen surface is prone to damage. Therefore, it is particularly important to improve the service life of Flip Flow Screen mesh. To solve this problem, we can start from the installation method.
Installation Methods For Flip Flop Screen Meshes
At present, there are three main methods for installing the flip flop screen mesh: bolt fixation, pressure plate fixation and welding fixation.
- Bolt Fixation
This is the most common method. Screws are used to firmly connect the screen mesh to the crossbeam to ensure its stability. However, under the action of long-term alternating loads, the screws are prone to loosen, resulting in the detachment or displacement of the screen mesh.
- Plate Fixation
This is a more reliable installation method. By using specially designed plates, the screen mesh is tightly pressed against the crossbeam, effectively preventing the possibility of bolt loosening. At the same time, the elastic design of the plates can also absorb some vibrations, reducing the risk of damage to the screen mesh.
- Welding Fixation
This method involves directly welding the screen mesh onto the crossbeam. It is the most secure approach. However, during the welding process, local high temperatures may be generated in the screen mesh, which could affect its material properties. Therefore, strict requirements are imposed on the welding process. Additionally, it is not easy to disassemble and repair after welding, making it less suitable for scenarios where the screen mesh needs to be replaced regularly.
In conclusion, in order to extend the service life of the flip flop screen mesh, it is recommended to install it using the method of pressing plates for fixation. This approach not only ensures the stability of the screen mesh but also effectively reduces the impact of vibration on the screen mesh. Of course, the specific choice of installation method should be determined based on the actual working conditions and usage requirements.
