The filter screen of sintering screen is stamped with standard 5-layer sintering screen. The filter screen structure is divided into four parts: protective layer, filter layer, dispersion layer and skeleton layer. It has uniform and stable filtering accuracy and high strength and stiffness. It is an ideal filter material for occasions requiring high compressive strength and uniform filtering accuracy. Because its filtration mechanism is surface filtration and the mesh is smooth, it has excellent backwashing and regeneration performance and can be used repeatedly for a long time. It is especially suitable for continuous and automatic operation process, which is unmatched by any kind of filter material. The material is easy to form, process and weld.
