With the emergence of large mines, the production capacity of table is increasing, and the material entering the vibrating screen is also increasing, and the particle size required for screening is also increasing. In order to screen the stones and sand that meet the building standard requirements, the general building aggregate production line is first separated from the stone soil, then crushed, screened and sand made, sand washed, dewatered, sewage treated and so on. In the case of high clay content, the clay is very harmful to the screening machine, the crusher, the vibrating screen and the sand making machine. Especially when a large amount of clay is crushed, the vibrating screen and the sand washer, the wear parts of the crusher are easily damaged, the screen plate is easily blocked, and a large amount of clay is mixed into the sand, which brings work intensity to the sand washer, and the sand washer is not clean, which reduces the quality of machine-made sand. At the same time, the high clay content also increases the difficulty and investment cost of environmental dust collection. In the production of high-quality machine-made sand, water-washing vibrating screen is needed, and water needs to be sprayed on the screen cloth. For machine-made sand with a particle size of 3.75-5mm, the screen cloth has a small aperture, so the steel wire diameter of the screen cloth is also small. Generally, 4-5mm diameter spring steel wire is used to weave the screen cloth. Since the screen cloth is above the screen support plate, it is indirectly in contact with the screen support plate through the damping rubber pad, that is, the top of the screen support plate is covered with a rubber pad, the screen cloth is placed on the rubber pad and supported by the screen support plate, and the screen support plate is welded to the vibrating screen box support frame. However, when the damping rubber pad is worn out or abnormally cut, the screen cloth will be in direct contact with the screen support plate, which will cause the screen cloth to be abnormally cut, thus greatly reducing the service life of the screen cloth.
