Vibratory screens have a very wide range of applications, covering almost every aspect of daily life; various types of vibratory screens are needed in processing and manufacturing! ; B’ v/ _# P4 L3 k% t’ v Vibration screens are primarily used in industries such as mining, coal processing, metallurgy, building materials, refractory materials, light industry, chemicals, pharmaceuticals, and food processing. : The M/z/R4 B8 T5 N1 type vibrating screen is the most widely used in mineral processing plants. Depending on their drive mechanisms, they can be classified into the following types: eccentric vibrating screens, inertial vibrating screens, self-centering vibrating screens, and resonance screens. Polyurethane elastomers are an upgraded version of polyurethanes, representing an important innovative technology in the field of modern coating applications. Sprayed polyurethane elastomers have excellent properties, similar to those of rubber: they are wear-resistant, highly elastic, and strong, and their areas of application overlap almost entirely with those of rubber. Compared to rubber, it has certain advantages, such as good plasticity, which allows it to be used to create various items as needed ; It has a wide range of hardness levels, allowing it to meet different hardness requirements. Specifically for vibrating screens used in mines, the advantages of elastomeric polyurethane in this field are even more evident. It has a high elongation rate and a wide range of hardness levels; its wear resistance, biocompatibility, and blood compatibility are particularly outstanding. At the same time, it also possesses excellent properties such as oil resistance, impact resistance, low-temperature resistance, radiation resistance, load-bearing capacity, heat insulation, and electrical insulation. Sprayed polyurethane possesses excellent properties such as wear resistance, water and oil resistance, vibration absorption and noise reduction, high strength, and strong adhesion to metal frames. It produces low levels of noise, offers good self-cleaning capabilities, reduces the load on screening machines, saves energy consumption, extends the lifespan of these machines, and ensures high-quality screening results. This polyurethane elastomer material is almost the ideal non-metallic material for mining applications, and it can even replace some metal materials. Spray-applied polyurethane elastomer. This elastomer specifically addresses several issues associated with polyurethane elastomers during the construction process, while fully preserving the superior physical and chemical properties of the original material. The Shore hardness of this wear-resistant coating varies widely. It ranges from Shore A45 to Shore D60. The hardness can be adjusted according to different operating conditions; by increasing the content of polar groups, hydrogen bonds are utilized to enhance the intermolecular forces, thereby effectively extending the effective lifespan of the coating. In addition, this material can not only effectively resist erosion and cavitation wear, but also withstand corrosion caused by strong acids and bases within a pH range of 3 to 11. This material not only protects against water erosion and cavitation wear on the surface of components, but also shields them from corrosion by acidic and alkaline substances; it is truly a versatile surface treatment material. This material is highly versatile and is widely used in various industrial fields where anti-corrosion and wear-resistant protection are required, yielding excellent results. It has been proven that this material bonds very firmly to the substrate; generally, the lifespan of the coating is more than ten times longer than that of ordinary metal materials, resulting in considerable economic benefits.
