String-type anti-blocking screen

The principle of string anti-blocking vibrating screen mesh: expand the two-dimensional fixed hole of the plane to the three-dimensional changeable mesh, and use the secondary vibration generated by the adjacent screen strip in random vibration to establish an effective vibration difference. To realize the continuous change of the screen hole in the screening, there is relatively no fixed critical granular stone, the specific method is to set up a relatively large vibration amplitude of the moving screen strip in the two relatively immobile static sieve strips, the moving screen strip can bounce up the stone during the jamming period or make it sieve.

According to the characteristics of the stone, the relative elastic strength and vibration amplitude of the static and dynamic screen strips are adjusted accordingly, which can make the screen in a good screening state, and the screening efficiency of the anti-blocking screen can be increased by about 30% compared with the fixed mesh screen, which basically realizes the self-cleaning function of the screen and greatly reduces the blockage of the screen hole. 　　

The static screen strip of the string anti-blocking vibrating screen is thicker than the dynamic screen strip, so it not only increases the wear resistance of the screen, but also improves the screening efficiency. At the same time, the screen structure of the anti-blocking screen can minimize the contact point between the stone and the screen hole, and reduce the occurrence of plugging holes.
