Highlights:(1) it uses cylinder-type eccentric shaft and eccentric block to make strong vibrating force. (2) beam is connected to the main body with bolts, has the feature of high strength. (3) the side plate of the screen box use the steel which make the boiler, the steel have high strength and strong impact-resistance. (4) it adopts the structure of small amplitude, high frequency, large obliquity to make the screen with high efficiency, large handing capacity, long life span, low consumption, and little noise.
