The main structures of a vibrating screen are as shown in Fig. 2 (a). It usually consists of a screen body, a screen surface, four groups of vibration isolation system, and an excitation system (i.e., a unilateral-driven system and two box-type exciters). The screen body is a composite structure composed of two side panels, an …
DZS linear vibrating screen is driven by double vibration motors. While two vibration motors doing synchronous rotation or counter¬rotation, the exciting force generated by eccentric block is cancelled out with transverse exciting force, and the longitudinal exciting resultant force is passed on the whole screen surface, in this way, the motion track of …
