Rubber U-shaped vibrating screen sealing strip has low cost, stable performance, small elastic modulus, high elongation, good elasticity and compression deformation resistance, and can adapt to a certain degree of vibration and deformation. It is generally suitable for conventional screening operations without special requirements for material characteristics, such as ordinary ores, coal, etc. The vibrating screen sealing strip can block external dust, moisture, and other impurities from entering the interior of the vibrating screen equipment, maintain internal cleanliness, reduce equipment failures caused by impurity intrusion, and extend the service life of the equipment.
