What are the differences between polyurethane screens and manganese steel screens? You can choose according to your actual needs.
What are the differences between polyurethane screens and manganese steel screens? You can choose according to your actual needs.
1. Service life: The polyurethane screen is made of wear-resistant rubber material, and then the steel plate is used as the reinforced skeleton. Combined with the elasticity of the rubber itself, the vibration and impact between the screen material and the screen are greatly reduced. Therefore, the service life of polyurethane screen is several to dozens of times that of manganese screen.
2. Weight comparison: Polyurethane screens with the same screen size are lighter in weight than manganese steel screens, and the light weight has a smaller load on the vibrator, less energy consumption, energy saving and environmental protection.
3. Maintenance and replacement: The service life of polyurethane screen reduces the number of screen maintenance and replacement, but the service life of manganese steel screen is usually 3-4 months, and the number of maintenance and replacement is more.
4. Process: The manganese steel screen is handmade or woven on the loom, and the ratio of weaving holes is relatively high, while the polyurethane screen is cast and needs to be left. The opening ratio of manganese steel screen with the same area is more than 32% higher than that of polyurethane screen.
5. Product price: Polyurethane screens are more expensive, and manganese steel screens are cheaper. In general, both have advantages and disadvantages, and you can choose the appropriate corresponding screen according to the actual situation of the screen material.
The difference between polyurethane screen and manganese steel screen:
First, the production process: the polyurethane screen adopts the casting process. Generally, there are machine casting and manual casting, which need to leave edges, while the manganese steel screen is machine-woven or hand-made.
Second, the weight of the product: the raw material of the polyurethane screen is a polymer synthetic material, so that the polyurethane screen of the same size is much lighter than the manganese steel screen, and the light weight consumes less energy for the machine, and the load is also Relatively small, prolonging the service life of the screening machine.
Third, service life: The raw materials of polyurethane screen have the characteristics of high wear resistance, high strength, high elasticity, and strong bearing capacity, which greatly reduces the vibration and impact between the screening material and the screen, so the service life is long . The service life of polyurethane screen is several to dozens of times that of manganese steel screen.
Fourth, maintenance and replacement: Due to the relatively long service life of polyurethane screens, the amount of maintenance and replacement in later use is greatly reduced, while the service life of manganese steel screens is usually about 3 months, and the number of repairs and replacements Also relatively more.
