The screen is constructed with 3 layers: the sieve cloth layer, the middle layer and the support layer. Three layers are bonded firmly by special glue under high temperature. The design of multi-layers enhances the integral strength of the screen and prolongs its lifetime. Moreover, different meshes from each layers matched accurately and reasonably, making the separating effectiveness better, which not only ensures the strength, but also enlarges the effective area of the screen.
