Yks serial circular motion vibrating screen is widely applied in material grade operation in coal, mine, metallurgy, chemical and building material industry. Yks circular motion vibrating screen is designed by combining actual demand of production on the base of absorbing international new technologies and structures. They are: The screening machine is mainly composed of screen box, vibrator, supporting system and motor. The screen plate includes pur plate, punched plate, round steel welding plate and stainless welding plate and so on. Block eccentric-type vibrator can adjust amplitude by adding or reducing weight plate within a certain range. It adopts flexible coupling and tire coupling in connecting vibrator and motor. It adopts rubber spring in decreasing vibration. It adopts tor-shear type high-strength bolt in connecting beams and lateral plates. It adopts nylon nut locking, etc. As buyer's requirement
