The biaxial round vibrating screen, with the patent number of ZL 2009 2 0224028.8, is utilized within the business of metallurgy, mine and coal. It is principally made out of screen box, screen, and vibration exciter and damping spring. The vibration exciter, collected in the side plate of the screen box, is determined by two engines through coupling turn to bring divergent dormancy energy lastly vibration. In addition, the side plate is bolted by HUCK jolts without weld and could be dismantled. The covering plate produced using polyurethane, fired or steel offers a high hostile to wear execution. In addition, the damping framework is underpinned by a composite spring
