Description

technical field [0001] The invention relates to the technical field of screens, in particular to a noise-reducing, high-temperature, corrosion-resistant polyurethane screen. Background technique [0002] Screening system equipment mainly includes vibrating screen, spiral classifier, feeding belt machine, etc. Among them, the noise of the vibrating screen is more prominent, and the noise value of the screening system is greater than 100dB. In the production process, the vibrating screen adopts polyurethane screen instead of the original metal screen, and uses wear-resistant rubber lining to increase damping. Noise has been reduced to a certain extent. In addition, the following noise control measures are taken. The sand and gravel processing system consists of a variety of equipment. The noise source is multiple sound sources, and the barrier of the mountain to the noise should be considered as much as possible during the layout. Use the terrain to arrange high-noise equ...
